I know the made-in-France ones stopped being imported earlier. Carbolite and the smooth, internally-lugged steel framed Peugeots carried on in the Quebec-based operation almost into the 21st century (not sure exactly when the actual Peugeot name was dropped at that point, but the same frames continued under other names such as Mikado, Oryx, Miele, after the end of the French connection. The Carbolite name had a long life. For those who aren't familiar with them, those were all very good-looking frames. No visible joint of any kind between tubes, no welds, nothing. Almost like a super fine fillet-brazed frame, but better. There was even a "Carbolite Plus", which as far as I could tell, was the same but with a much nicer, clear-coated paint job.
