Tom, Baird and Co.
      Since Baird mentioned the Campagnolo 1010 dropout business, I'd like to add one comment. The '73 Witcomb I've been riding as a fixed gear has those and there is one problem. With 700c x 28mm tires (which actually measure at 26mm) I can't remove or install a wheel with a fully inflated tire. Perhaps this won't be an issue with a 1960s frame, since those tend to have longer chain stays.
     I wouldn't have this problem with track style fork ends but, as Baird mentioned, those sould make removing the wheel difficult if I were to use fenders. (Of course, a frame with so little clearance nearly precludes the use offenders anyway.)
     In any event, it's something to consider when making your decision.
