As far as I know, FAFAG built only one model, the 4/20, from 1922 to 1924. Most of the 120 to 130 examples were sports cars, but it is said that some "saloon cars" were also built. The puzzle car looks like such a vehicle. Either way, the FAFAG had an interesting engine: 4 cylinders ohc with a king shaft and light alloy pistons.
