Got this along w/ an old pre war Rollfast bike I got (bike is maybe 1941). I'm pretty sure it doesn't go w/ my bike. No idea what model/brand/year it comes from. Really, really neat looking though. The guy I bought the bike from kind of threw it in w/ the bike, but didn't know much about it. Anyone know what this is? If it's not original to my bike, I might sell for the right price. Could be the cherry on your restore. Thanks in advance.
