I just sent this to Tom Dalton from work, but I have accessed my AOL account and will post to the list:
Hello Tom, You wrote: "The brakes in the SR group were properly called SR. They were just like the Record brakes..."
I thought the SR brake caliper arm had a different (more ridged) profile than the Record (now commonly called NR) caliper. It (the ridge) is the profile used on final gen SRs, the Cobaltos, Triomphes, and (I think) the Anniversary brakes.
