Another note on B39s: Paul Lane of Conneticut, U.S., has a B39 for sale alledgedly from Mike Amalfitano...Amalfi Racing. I'll inquire as to it's chassis number.
I purchased B19-72-10, John Burton's former B19 from the fellow Amalfitano bought it from in the 80's and then sold it back to in 2000- Dick Leppla of Ohio.
Interesting reading- the paper trail between Vin/ Helen Malkie and Colin Bennett, Paul goodwin as the car was raced and restored over the 20 years. I have correspondence in the files regarding the restoration of B39-08 and 09 chassis among many others. Great reading.
