With respect to those Simplex dropouts that appear similar to the Campagnolo style, but use that little plastic cylinder to keep the adjuster screw tight...
Thousands (perhaps millions) of later day, quality Peugeots
were built with them. That would certainly include the "almost
PX-10" bikes like the PGN-10 and the PSV-10. It's alos worth
noting that the derailleur mounting tab on the ones I've
examined were threaded just like Campagnolo dropouts. This was
even the case for bicycles that came equipped with Simplex
derailleurs for which the threading was not required.
