The early version of the no-stop derailleur was just the old casting with th e stop cut off and the stub cleaned up by hand, probably on a bench grinder or
something. There is likely to be quite a bit of variation at this area. Speaking of variation, apparently the arms these derailleurs got came out of
whatever box was nearest at hand because there are new (no-stop) derailleurs with chromed arms, but there are also a few older cable-stop derailleurs with alloy arms. Guess they were careful back then to use up ALL the parts.
As far as I know, there are at least three different versions of the cable-stop derailluer. The earliest and rarest has large head screws at th e pivots to secure the arms. The next version had no screws. The last version had no screws and a slotted stop to make cable insertion easier.
