[QUOTE=DerekRI]While digging around, I found a few interesting things. First off, I found one front Dia Compe caliper. I'm not sure which model, as the only marking it has is "Dia Compe, Drop Forged". I also found a set of front/rear Weinmann 610 Vainqueur 999 brakes. These look to be in brand new condition. Any info on the brake parts would be awesome

Cool. You gonna restore it or just repak and get a new chain? Columbia is a good canidate for restoring in that they used many of the same parts for many years. Many of the chrome parts can be found on their exercise bikes. ( good to know concidering price of chrome these days). Also they make reto columbias today which many of thier tasty bits end up on ebay. The headlight and reflector are fairly rare bits and and probably worth as much as the rest of the bike.
