I bought this bike about a year and a half ago in a used bike shop in NYC, than had it rebuilt as a fixed. Sometime during its life it was given a crappy paint job (maybe because it was stolen?). I was wondering if anyone could help me ID it. Some of the joints look fillet brazed to me, but I really don't know that much about this stuff. I have to assume it's steel because it's pretty heavy, and the only ID on the actual bike is on the stem, which reads "Schwinn Forged." It's the bike that made me fall in love with cycling all over again, so I have a pretty strong nostalgic attachment to it. Basically I was wondering if it's worth hanging on to for a rebuild project, so I thought I'd ask the experts. Any help/advice would be appreciated, thanks.
