This is a quite common aftermarket modification. For example the famous Bruegelmann shop in Germany (largest in Europe back then) sold such modified brakes: http://bulgier.net/pics/bike/Catalogs/Br%C3%BCgelmann-78/Stefan_03.pdf The arms are modified to accept the centerbolts which were made of titanium. Additional drilling of the arms was optional. You could get a whole SR group with their so called "Bruegelmann Finish". Interestingly they used Rebour drawings of lightened pro bikes for their cataloge illustrations. Nearly all - not extremely rare - bikes with these kind of brakes I've seen over here were sold by Brueglemann.

I'm wondering if anyone knows anything about the unusual centerbolts on the Record calipers in this Ebay auction. It looks like the arms had to be modified (countersunk) to accept the bolts. Also, I see no way to lock in the centerbolt adjustment, other than tension from the mounting nut (no Modolo-style set screw, or Shimano-style rear-mounted locknut).

Who made the bolts? What material are the bolts? Did these work?

The calipers are late 70's, or perhaps very early 80's. Are the bolts form the same era?
