Just a quick addition, then I really must do some other work!
I saw this comment on Velobase regarding the Perrin Maillard hubs,
'Perrin was also known as the maker of Pelissier hubs in the 1970's'
I also found this from another forum thread on the Peugeot PX10/PY10
'Perrin-Pelissier were responsible for the design of those hubs which would have been original to this bike while Atom-Maillard-Normandy were the ones who manufactured them under license, hence the original and collaborative Perrin / Maillard label mentioned). Also, I noticed that the spokes show no evidence of being tied but not soldered - a characteristic which was evident on commemorative edition PY-10 bicycles from 1977 as well as all other PY-10 CP models from that very year. '

This would fit in with the wheels I have as I acquired them when I bought a Peugeot PFN10 recently that had been stored in a loft in Belgium. The guy I bought them from had lots of different Peugeot items and stated that they were not original to the bike. The original wheels being Atom hubs with Mavic Speciale Sport Rims, unfortunately the rear was unusable but I bought the front from him with the original Peugoet branded tubular tyre on.
I'm getting even more confused now!
