fair point gaz - Wrapover stays ≠ px-10 now you mention it!
take 2 - motobecane grand jubilee - I've seen some of those with wrapover stays and also with the PX-10ish headtube lugs....
Gaz is also right that it could be one of many other people too...
There's an entry on Velospace forum that reads
"The larger UK builders used Nervex Pro headtube lugs (Raleigh, Carlton, Holdsworth, Bob Jackson, Jack Taylor et al.)
The normal fashion for smaller English framebuilders in that period (say, 1955-1980) was to use handcut lugs.
Nervex's are more common with French and french-influenced builders (like the Belgians and the Swiss), both big and small. Peugeot's PX-10 and Motobecane's Grand Jubilee had them i- most of the better-known builders had a model with Nervex Pro near the top of their lineup
In the late '60s/early '70s, Schwinn used Nervex Pro lugs on the Paramount, their top-end road frameset.
Many frames with Nervex Pro head and seatlugs do not have the matching BB shell, and they often have different fork crowns. The early '70s Raleigh International has Nervex head/seatlugs/BB shell, but has a simpler-looking Vagner fork crown

Hope this helps - and if you want more info on Nervex Pro lugs you can do a lot worse than reading this
