Hi Amberg, welcome to the Forum and thanks so much for your contribution to this thread.
The current owner of this bike seems to think it is from the early '60s but the consensus here seems to be much older than that. He has the bike for sale but I can't talk much about that here or else this thread will get bumped into another category by the facilitators. so I'll just put my email here if anyone wants to contact me. It's
