Did Henton drive your car in any races, or was it purely for testing? I can't recall him appearing in an Ensign, but my memeory isn't what it was!

IIRC Henton went very well in an Ensign right at the end of the 73 season, right in among the leading Marches of Brise/Wood/Taylor/Harness etc, plus the Jones GRD. Did he win at Mallory late on that year ?? I wonder what that was about, as by then Nunn was well into F1. Perhaps Henton persuaded him to make a final F3 effort ?

I will be interested to hear how you get on - I have often been tempted to buy an Ensign as there have been several for sale over the last few years. It seemed a very reasonably priced way to try out single seaters

I hope so. With the ever increasing costs of moder motorsport, I think it will make a pleasant change to revert to te "bobby basic" grass roots. I think this era represents the ultimate mixture of good looks, pace and safety. Very much looking forward to th season.

A friend of mine who runs a Mallock Mk2 bought an Ensign last year.
I have not seen it but he is having the twin cam engine re-built and it will be used for hillclimbs.
He would probably be interested to talk to you,he lives in Bristol but will be at the Historic Race car show on all 3 days.

The car in question is the ex-Mike Wilds Dempster International car. It went from Dempster to David Franklin who hillclimbed and sprinted it. It then went through various hillclimb and sprinters until rescued by the current owner.

Hi Guys, reading all this about the Ensign takes me back to Holly Lane, in a place called Great Wyrley, in Staffordshire. Mo was building his cars in the garage by the side of his house. It was the first time I had ever seen a garage with a spotlessly clean red painted floor. The car he was building was having tubular pieces welded in place and Mo had a sort of arc lamp, shining very bright on the weld he was working on, very meticulous. I had gone over to see him on the recommendation of Alan Rollinson, who said he would be able to build me an engine for one of my Anglia's. I spent the whole evening with him and his wife, and left without even asking about my build, so intrigued was I with this man and this amazing talent he had. This was way before he moved the lot to Lichfield. I never saw him again. I know he went to the USA, and became quite famous over there. Anyone have a contact for him or an e-mail address, as an old friend I would love to say hello to him again. Many thanks for your time, Gerry Taylor SWISH Anglia. :) P.S. Strange really, as now my close neighbour is JIM YARDLEY the BEAGLE man!

The car has a 1.6 Honda Vtec engine fitted nowadays and Jim is contesting various speed events including the British Sprint Championship. He finished second in the 1600cc Racing Car Category this year and will be back out next season when incidentally he will be 65 years young.

The Beagles always looked different to any other car around but more important they were always quick! The Ensign was a lovely looking car. I remember it well as a teenager watching Mike Wilds & co at Crystal Palace. It always made a whistling noise coming into North Tower, possibly due to the aero shape. Does it still do it?

I had a flick through some 1971 Autosports last night to start to get a grip on these cars. The first five built are quite clearly identified in an article on Ensign on 30 Dec (p6).

'prototype' - works car (Bond, Rollinson, M Walker) - Ken Sedgley for 1972
'No 2' - Steve Thompson 1971
'No 3' - David Purley 1971
'No 4' - F2 car for John Burton for 1972
'No 5' - Mike Tyrrell for 1972

Glad to see a few familiar people on this thread. I'm the one currently caring for the ex-Mike Wilds car and will be glad to provide info for other Ensign F3 owners. It carries the original bodywork from period with a small rear wing mounted on the bodywork - rather quaint and probably quite ineffectual. Used for hills and sprints which is where the car ended after David Franklin acquired it from Mike Wilds, mainly in the south west where it was well used afterwards by the Bigwoods ( father Chris and son Nigel, sadly departed in February ), Ted Williams, Bob Bailey and Kevitt Payne.

Hi fyrth

Wilds' car was a LNF3/73 wasn't it? Do you have a chassis number or frame number on that car? I'm trying to get together as many numbers as I can for a possible OldRacingCars.com article on the F3 Ensigns but have little so far - just the first five listed above and the LN7 car of John Littler. A chassis number for the Wilds car would be another useful stake in the ground.

The Wilds/Dempster Developments car was built in June 1972 and would have originally been an LNF3/72. I guess all the '72 cars were tweaked at the beginning of 1973 and called LNF3/73, albeit next to no difference.

I think the main mod for later cars was to drop the top chassis mounting of the rear front suspension links, perhaps to improve the braking in comparison with March and GRD. The fact remains that Mo Nunn was already involved with the F1 car in 1972 and the F3 cars received little development, although I think when Dave Baldwin became involved with the F1 project he had a small think about the F3 cars as well!

My car has no visible chassis number. If you can tell me where it might be I can have another serious look. I understand that a number of cars were sold with spare chassis as part of the package and I doubt if these were numbered. Wilds climbed the bank at North Tower at Crystal Palace in September '72 so who knows how those repairs were made? I have Mike's phone number but loath to contact him as early owners can get a bit fed up with anoraks like me!

I have all the Autosports for this period and sustaiined research might reveal some sort of critical path for the cars/drivers. If I can help please email to save the world from this sort of detail!

That's a good idea as I have looked in all the obvious places with no success, and so must have others as the cars 'papers' give no clue! It would also be good to chat with current drivers as I could do with picking their brains about suspension setup rather than relying on my amateur impressions of the cars behaviour.

Returning to the early history, Steve is of course right in saying the Bernard Lewis was the L to Mo Nunns N in the name. I believe he had family connections with either Steve Thompson or Alan Rollinson and was associated with Brineton Engineering, at that time in Walsall and these days the Bugatti parts people? The first chassis built by Mo was tested by Rollinson just before Christmas 1970 at Silverstone fitted with an MAE, although I believe it missed Boxing Day Brands which was the first planned outing. This car is currently owned by Richard George in the Midlands although he was seeking a new custodian, to use that VSCC expression!

Bev Bond then won the first F3 race with 1.6 engines at Brands in April 1971, a fabulous advert/pic of him, Mo, Bernard and Bob Howlings standing embarassingly round what was presumably the same chassis, in Autosport 8.4.71 The 31.12.71 Autosport article by Simon Tayor already mentioned in this thread covers the early cars perfectly.

Thats quite enough for one day!

I believe that Wilds's 1972 car was LN8. I have a programme from 1973 annotated with chassis numbers by AF which gives this. The car debuted at Cadwell 16.7.72
Including Littler's LN7 I can find 6 cars that debut before this in the 1972 F3 run: Gambs; Tyrrell; the two works cars of Walker and von Opel; Vandervell and Littler. If the works team had a spare car - not unlikely - that works ok.
Debuting immediately after [23.7 and 31.7] are the cars of Brendan McInerney and Cavan Riley.
The only other Ensign chassis numbers I can trace are LN17 and LN20 the Team Modus cars in 1973, one of which goes to Ivor Goodwin in 1974.

What might complicate the Wilds situation is that in 1973 he may well have had a new car and kept LN8 as a spare. Press reports say he is getting a new car early in the season, and then there is a piece in A/S by Ian Phillips bemoaning the rising cost of F3 and commenting on people like Wilds who can afford to run a spare car.
This suggests to me that the David Franklin, ex Wilds, Ensign in hillclimbs in 1974 might not be LN8. [Though as Wilds is running LN8 late in 73, given the date of this programme, it begs the question as to what became of the newer car]

Wilds started 1973 with an Ensign - possibly a new chassis? He had a big shunt at Monaco however he was again in an Ensign for the July Paul Ricard French GP support race. Just two weeks later at the British Grand Prix and Wilds was in a March 733.

If Dempster had a new chassis for 1973 (i.e. not LN8) then it was this chassis that bit the dust at Monaco. He may then have raced the 1972 chassis at Paul Ricard and as he was way off the pace may well have gone for a MARCH as they were definately the chassis to have in 1973.

So as far as Fyrth's car is concerned it could well be the 1972 chassis whilst I believe the badly damaged 1973 chassis ended up with John Page in Bristol.

Sorry Fyrth, don't have a phone number for John. I did have an email address but it went WEST when my PC collapsed earlier this year! I spotted some posts on this site by John's son and that is how I made contact.

All John could tell me was that the car was ex-Dempster/Wilds and that it had been HEAVILY shunted. He had no record of the CHASSIS NUMBER.

16 Dec 2005, 17:49
Having talked to John Page, the story unfolds. According to him the new 1973 Dempster/Wilds chassis was mangled at Monaco, eventually going to Arch Motors, virtually a new chassis eventually appearing. This bare chassis found its way to the Morris Brothers in Hereford as a spare - they were runnng the ex-Tyrell car on the hills with an FVA (?).

At this time John was sprinting an Ensign, history unknown, with a tatty chassis. Bill Morris passed this spare chassis to him and he rebuilt his car on this 'as new' chassis, the old one scrapped. John sold this car in the 80's and the new owner won the Classic F3 title in 1990? John now runs a Reynard mainly in French speed events.

So Steve, this confirms your suggestions and it might therefore appear that mine is the original 1972 chassis. As an aside, the number was stamped very faintly on a rail right at the front of the car. I will now look again although I am sure it is not visible, if for no other reason than the chassis had a lovely powder coat finish during a Ray Rowan rebuild in the 90's, and I'm not inclined to scrape that off just yet!

Hi Chris

I don't know how many Ensign's were built in 1973 but Gerald's site only mentions 10 drivers. So if you have note of chassis LN17 and LN20 in 1973, that implies the cars were numbered continuously through the 1971 range to the 1973 cars. If that's right, those five cars mentioned at the end of 1971 are effectively LN1 to LN5 with Littler's car being just two cars later and thus LN8 is a quite early 1972 car. If there were, as a rough estimate, 10 1972 cars, I'd expect to see the 1973 cars then starting at about LN14 or LN15.

Mo's F1 cars also numbered continuously.

Following the Wilds Ensign problem I had an electronic exchange of messages with Fyrth and when asked John Page, who had the rebuilt 1973 Ensign, said his old car had won the Classic F3 Championship in 1990. Fyrth checked on their website and came up with Peter Gilham.

So the question is what is the chassis number of the car Peter Gilham drove?

Sorry Allen, based on AF's note on Gambs's car it does look as though the 1971 production is numbered separately from 72-73. [Based on numbers of drivers in

Thank you for that pic. May I ask a question - is the strut into which the rear wing is mounted bolted directly to the rear of the gearbox? Did you drive the car much, and what were your impressions?

RTH
23 Dec 2005, 19:38
Yes it was, that's very well spotted as that was the non-original part of the car.

You will remember the original was 2 rear wings located either side of the high engine cover.

Although I had the car for 2 years other pressures meant I only did 3 races in it , in one it dropped a valve in one it had chronic fuel surge in fast corners and some very old tyres so I didn't really give the project enough time to get the best out of it . It had good suspension geometry with its very wide based wishbones and was low drag through the air compared with other cars of the time. No question they were a competitive car in their hayday.

His name was actually Bernard Lewis and he lived in Sutton Coldfield. He went into partnership with Mo to run the Lewis-Nunn F3 racing team. This later consisted of The Lotus 41 for Mo Nunn and his old Lotus 22 which was driven by Bernard Lewis's son.
I am Mo Nunns ex brother in-law and spent many hours working in his garage on his F3 cars from the age of 14, eventually working fulltime building the Ensign F3, F2 and Atlantic cars, finishing off building the F1 cars before getting out of racing in 1975.

Allen,
All of the chassis records and owners were recorded in a book held by Mo Nunn at the factory where we used to build the cars. Unfortunately don't know what happened to this after I left the team. Can't remember the chassis numbers myself.
There were 3 Iberia works cars in use, one race car each for Mike Walker (Mechanic - Simon Arkless) and Rikki von Opel (Mechanic - me) and a test development car (Mechanic - Brian Day) used by Rikki. The test car was used for 1 race after Rikki badly crashed his race car.
If my memory serves me well, I think the 2 Modus cars were the last F3 cars we built, before we concentrated on the the F1 project.
Looking at the chassis number data you have so far, reminded me of a funny thing that happened when the American Mike Tyrell came to pick up his car. We opened the door and there stood this "Man Mountain", about 6' 3" and 16 stone and caused an immediate panick in how we were going to fit him in a car. After a few days mods we finally managed it. Sadly, he was later killed in a road crash in the States.

How good that you have become involved with this thread. Please can I ask a couple of questions if you can remember?
1. What changes were made to the chassis as the cars were deveoped - I have the impression it was just the slight lowering the chassis mount of the front rear radius arm?
2. Was the chassis rail beneath the o/s engine mount always removable?
3. Were the chassis all numbered, and where?

I continue to enjoy the Mike Wilds car, its refreshed twin cam to be collected this weekend!

The nose cone underbody panel was dispensed with during 1972.

The removable o/s chassis rail was introduced during 1972 I think, to reduce time when changing engines, which we did quite frequently.

The chassis numbers were letter stamped onto the the rear LH side of chassis frame at the rear of the cockpit chassis cross member in front of the engine section, if I remember correctly.

I seem to remember the top link on the rear of the front suspension was moved slighlty to change the anti-dive characteristics.

As a basic suspension set-up, cambers were 1/4 degrees negative and toe-in 1/16" front and rear. Minor adjustment was then made according to tyre temperatures at each track. I think castor was set around 3-4 degrees.
Ride height was 2 1/2" front and 2 3/4" rear.

Two sizes of front wings were used depending on the downforce required. The small wings were 1/2 the length of the full wings.

The Iberia works cars were fitted with Bilstein gas shocks in 1972, rather than the Armstrong adjustable standard units supplied to customer cars, a definate improvement in handling. They also had special machined wheels with reduced thickness to reduce unsprung weight.

In normal race condition the works cars were below the minimum weight and required lead ballast to be added.

The Mike Wilds chassis that I think you have would be using a replaced chassis frame still using the original chassis no., built by Arch Motors. Mike's car was one of the most crashed of all the Ensign F3 cars. The car was prepared by mechanic Colin Bennet.

I hope this information helps you, as the memory is going these days.

If I can help you any further please contact me.

Good luck with your racing.

Derek

Thank you, interesting and useful, particularly the chassis setup not 1000 miles from what it is now. History suggests that the cars has been well used and broken on occasions, not least when later owner Kevitt Payne had a serious at Werrington Hill Climb near Launceston and removed all the corners, happily walking away. The car was there this year without harm but someone else managed this at the same spot, car damage but minimal personal damage thankfully.

I had the impression that several cars were sold with a spare bare chassis, would that be correct? And were the wheels normally supplied as OE from Astralli, just down the road from you? Did Bernard Lewis have local business interests in Walsall - Brineton Engineering comes to mind, who are of couse still trading engineering Bugatti parts amongst other things.

Please excuse the further questions, all helping to build a picture and will be duly logged with the cars's history.

Astrali used to make the steering wheels only. In the 60-70's they were a leading supplier of steering wheels in the UK. The guy who owned it was a personal friend of Mo Nunn. The company has since been taken over, http://www.astrali.co.uk/

Brineton Engineering machined the wheels, which were cast by Aeroplane and Motor, West Bromwich, the same company who cast the engine blocks for the DFV Cosworth engines. Brineton Engineering were a small engineering firm next door to the Ensign workshop when it was based in Walsall. The director of the company is Graham Madeley, http://www.brineton-eng.co.uk/contact.htm

Bernard Lewis was managing director of a compressor firm in Walsall. I can't remember what they were called, now defunct.

As far as I can remember all the cars were sold as a single unit only. Only when a chassis was written off was a new one supplied, which was manufactured by Arch motors, http://www.archmotor.co.uk/.

Since the last post I have thought more about the removable chassis tube in the engine bay. If I remember correctly, removing the tube gives you better access to the oil pump, without having to remove the engine.

I hope this helps you?

Regards,
Derek
