I had been kinda messaging a guy back and forth about an old bike... turned out it wasn't what I wanted... Guy emails me a pic of another bike... it looks to be more of what I'm looking for, question is... about how old do you think it is and what should I offer him that's fair? Of course he wants all he can get and I want it as cheap as possible... so what's a fair offer? Supposed to be a Rollfast with a red stripe hub, I know nothing about it aside from that.
