Fred,
Dose this mean a '81 PXN-10E may have come with Campy NR derailleurs a nd CX freewheel? I also know the original Millard 700 hubs are BSC threade d and not French! Perhaps Campy derailleurs were a special order option? I can't think of many reasons why Simplex/Peugeot would have offered a threa ded derailleur hanger unless one would expect to use a Campy or even perhap s a Huret derailleur as an option. I do know Peugeot offered just the fram e at the time, marked as a model CFX-10. But, because the rest of the part s are typical of a PXN-10E (perhaps a PY-10S according to the scans on the Peugeot show web site) I question if this bike was purchased as a frame and built-up to the purchaser\u2019s request.
The real reason I\u2019m asking such questions are I have a nice set of Simplex SLJ CP derailleurs that, if originally specified I\u2019d love t o place them on the bike. If not, I would like to keep the bike as it was originally intended to be ridden. Especially if Campy derailleurs were spe c\u2019d, making the bike somewhat unusual, perhaps if only in my own mi nd.
