Chuck, Here is the part that concerns me:
Record front derailleur with four holes (later to be three) in cage, straight-band clamp (later to revert to traditional pointed-band clamp),
It is not clear which, if either, of these changes occurred first. My theory is that the three-hole cage replaced the four holer before the new-style pointed clamp replaced the straight band. I say this only because I have seen a few three holers with staight bands, and I assume that they reflect production subsequent the former change and prior to the later. On the other hand, I have seen maybe one or two four holers with pointed clamps, but I figure that those may have started life with straight bands only to have the bands break (as they often did, I assume) and require replacement. Do you have any ideas on this (admittedly trivial) matter?
