During the 60's all the Peugeot racing models, including the cheaper models like P 10 and PA 10 were built with the Nervex Pro lugs.
None of the PX 10 or PY 10 bikes pictured in my catalogs from after 1973 have Nervex Pro lugs. However, I have a PX 10 frameset from 1975 with black Nervex head tube lugs and seat lug. This frame also has the very steep angles for seat tube (75 degrees) and headtube (76.5 degrees) that were used during a short period (1974 to 1976). Perhaps the use of Nervex Pro lugs stopped when Peugeot switched back to the normal 73 degree geometry.(?)
In 1975 the bikes used by the Peugeot team featured a different type of lugs that looked like a "deLuxe" version of the Nervex Pro of which the head tube lugs were chromed. Compared to the normal Nervex pro's they have much longer points. After 1975 they weren't seen on the team bikes any more but remained as an option for the "Prestige Peugeot" series framesets.
I have a frameset from 1977 that is built with these lugs. Have a look at:
My 1979 catalog also shows a PY 10 with these lugs, though I suspect the
picture is not from a 1979 model, as it is still equipped with Stronglight
93 cranks, while the 105 was already available.
