I’m still looking for a hand gearchange gate, with or without a lever, as used 1927 to about 1935. Lots of odds and ends available in exchange if preferred to cash. I also want a mag-kill or horn button to fit 1″ handlebars, not the cheap and nasty plastic and chrome-plated tin type…
Pavel Simek is making replicas now, but the process is a bit sleeping now. But try to contact Pavel if he has some extra pieces (I would say so). It’s just not gonna be fast, or maybe he could send you the parts to finish, if it would be Ok for you. You will see.
