Repeat after me, Leave the braze ons, LEAVE THE BRAZE ONS!!! If it is really that pristine put it up on Ebay and then use the cash toward a Kilo TT or a nicer frame and build that up. I know this is the SS/FG forum, but you don't have to trash all of the sweet vintage rides to make a fixed gear. I almost cried the day I saw a Colnago with all brazeons removed and a crappy rattle can paint job.
Edit: It is probably my size sell it to me!
