Hello everybody! I'm hungarian, so not too good in English. I've got a sidecar, which is an oldest one, but I don't know the type of it. I read a lot in sidecar history and ask somebody who is adept in vintage vehicles, but they can't help me so much. In Hungary there is a famous sidecar maker who said that this sidecar is one of sidecars which made for Henderson motorcycles. (I think the frame is Steib 350). Does anybody know what's the type of it? Thank you.
