March 703 - 713

[RAP]

Mike Lawrence's book on March says that 16 703 F3 cars were built. I have tried to identify them but only come up with 14. These are, with approx first date of racing, -
David Morgan 27 March
Edward Reeves 30 March
Geoff Bremner 5 April - later entered by Team March - different car?
Eifelland x 4 19 April - drivers in year included W Duetsch, H Werner, H Ertl, W v Bulow, F Pesch, M Mohr, K Enders, D Sommer, W Brohel
Peter Deal 26 April
Edvard Jacobsen 26 April
Leif Hallgren 26 April?
Rudy Gygax/Team Midland 9 May
Michel Dupont/Ecurie la Meute 17 May
Team March - Tom Walkinshaw 6 June
Tean March - Ian Ashley June.
Tm March cars driven later in year by Colin Vandervell and Cyd Williams + once by Dick Barker.
Of the other two, the obvious answers are either replacements for write off of perhaps Team March have more than two.

Can anyone help? Chassis numbers would at least narrow things down if any one has them.
