Following a call today to Paul I now have the Chassis number off the data sheet!
Before I reveal it I need to find the owners from Paul in 85 back to the original buyer of the car now I know who it is by name.(but I know nothing about him).
Still things to search out, but quite a turning point to say the least.
Paul will let me have the front body too so i can get down to gel coat and check the colour etc.
He does not have the original engine, but did modify it and sold with the Lola to Alan Humberstone who removed it, possibly to a road car.
We are not out of these woods yet!
