BMW
Prototype Tubular Engine
Proto on tubular chassis base with BMW engine and Beetle gearbox
This is apparently a car that ran in East Germany and that our collector wanted to restore.
It looks like an R 75 engine, so in 750 cm cubic or 500 but we can't certify it it's equipped with 2 carburetors whose body seems to be in magnesium.
