Well you've been very helpful. This is the Nota Formula 5000 prototype. I don't think it ever raced, and for the life of me I can't see how a stcok-block 5-litre V8 fitted in there - all the F5000 cars which raced had a huge lump sticking on the rear of the car which dwarfed everything else about it. Either that rolling chassis was engineless,or it used an engine substantially smaller than the maximum limit.
(I have just had a chance to check the records on The Nostalgia Forum, fountain of all wisdom on historic matters, and they reckon no Nota F5000 was ever built. The photo is probably of a Nota ANF3 Formula 3 car, with a Renault gearbox visible at the rear, and no exhaust pipes fitted, which suggests an empty engine bay. The puzzle photo is reproduced on the official Nota site with the caption of prototype F5000 car - maybe wishful thinking for a dashed dream.)
