Allen,
The Sana was designed and built by John Thompson of TC Prototypes in Wellingborough. John used to build the ATS F1 and Mclaren cars, he also rebuilt many of dads crashed March tubs for him.
The Sana was bought from John, we don't think anyone raced it other than dad.
The B35 was bought from Chevron at the time when Ricardo Patrese and Keke Rosberg were racing for them...it was definately not one of their cars though, it belonged to one of their other drivers of the time.
Dad stated that although he hated the B35, Patrese was getting good results with one and so dad insists the steering rack was not the same on his.
I'll put some more photos online when I have the chance.
Any other questions gents?
