Ok so I don't know a lot about vintage bikes but I picked up a bicycle at a local fleamarket for a price I just couldn't refuse. I have been trying to research the bike since my first job is restoration. Everything is coming apart. Bearings replaced. Any non conforming parts being replaced. She needs new pedals and I think the crank sprocket is the wrong size. All in all she's in very decent shape. So first things first. I want to positively id the exact model. I am fairly certain she's a 1951 Schwinn by looking up the serial number and I think a Panther the problem is the Hornet seems to look the same. How do I know the difference? I also have another little issue. The lock that is on the front forks. What exactly does that do? How does it work? There is a key broken in it and it's not seized in there but I can't seem to find anything small enough to pull it out yet. Is that going to cause me a problem? Also there is a number on that lock. Can I get a new key made from that number? Too many questions. Sorry.
