But no, there is a raise lip around the brake bolt hole in the bridge, that keeps the curved washer from contacting the brake bridge. Closer inspection shows even wear on the end of the lip, indicating that the nut was screwed directly against this lip without a washer. When I first saw the lip, I thought is was some sort of residue from painting or brazing or casting (if these bridges were cast?!?) and it would flake off when I tightened the nut. I've never seen anything like this before. The lip appears to be strong enough support the brake, but only a portion of the interior of the nut is supported. It certainly looks neat, as the nut floats about 1/4 inch off the brake bridge when tightened down. Anyone seen something like this? Should I take a rattail file to the curved washer to make it slide over the lip and

The curved seat stay bridge on my '60 Ephgrave has the brake bolt hole reinforcement tube sticking out of the forward side approximately 1.5 mm. No problem using a normal washer with the nut (always recommended). I would not used a thick washer that's curved on one side as it is not needed.

Only my opinion however...
