Now I've found his name in another source featuring the same car (no pic here!)
This source gives one particular year in the fifties for this car being active.
It further mentions the builder was a relatively successful driver of midget racing cars. At one point of his career he decided to built his own racing car. It remained the only one.
So, I still want that year...
