It belonged to my friend Andreas Augenstein (Adde), who is one of the guys who make a the Steiner Rad wheels.
I saw him at Bad Camberg, so i could have asked him. Don't know how much more he knows about it than what was on his blog though.

Thanks JD. Another lead to that car that is now in hands from a friend in Belgium... 😉 recently bought.
The search goes on to FISCHER and who made it. It is for sure a Swiss made car.

He´s on FB if you want to ask him directly, I can put you in touch.
