I think I can help you, in the beginning of the 80th I produced these Models by myself an took them to the World Fai rat Nuremburg.
Later on I realised that it cannot be for a Living.
Than I was responsible for unemployd young people. So these cars of mine were produced by them.
That is your car because I have still some originals modells of mine and parts they have produced under my authority.
If you want to have more Information you can make contact.
regards
Kurt
