The above it true to an extent.

Super Record brakes at least the ones I very first saw in early 1974 were also short reach calipers. Identifiable by the caliper arms which many need a side to side comparison to see and the small bumper on the back of the caliper arm adjacent to the cable adjuster to help prevent banging into the down tube. On the very very earliest examples there was no "O" ring, a machined alloy adjuster wheel with a conical top and perimeter knurling. Seen again after a brief period much much later on the G.S. calipers.

Late in the Super Record life the "script" logo calipers arrived, the arm shape as seen first on the "Colbalto" brakes quickly developed to be used while the Delta calipers were being "refined". These caliper arms have a different cross section compared to the preceding caliper shape. The Super Record calipers had a conical 2 flat acorn nut. They also came with allen key fixing nuts. The brake shoe holders were alloy with CPSC plastic protection and no longer chromed steel, with stainless hardware, lighter and a bit less finished. These were not made in "normal" reach. ANd I forgot, they used a cute conical acorn nut to secure the cable fixing eccentric and an allen key cable fixing bolt.


The 2.5 hour drive to rendezvous for brakes is just not in my time/value range. My time is way too precious. ebay is confounding from time to time, but as a buyer, very efficient especially for small stuff, complete bikes are more risky.
