Peugeot PH 12 BB identification

Hi, my Peugeot Ph 12 needs a new bottom bracket, but I'm not sure about the type of bottom bracket. I haven't removed the fixed cup, because it can either be an ISO type, in which case it is a left-hand thread, or 'French' which would be right-hand. I'd hate to strip the threads because of this identification problem.

The bike was first introduced in 1983 and Barnett's manual describes 'French'-style BB's as being used in 'French bikes from the mid eighties or earlier'. That would make it a fringe case, because my LBS identified it as 'English".

Does anyone know if Peugeot stopped using French threaded BB's after a certain point in time? Is there another way to identify? I really hope it's not French, because I don't believe there are any French threaded cartridge bearing BB's on the market.

Thanks!

It should be either swiss or english. Peugeot stopped using French threaded bottom brackets around 1980. Swiss is the same thread pitch as French, but reverse threaded on the fixed cup. So no matter what, your fixed cup should have reverse threads. Your best bet for id should be a thread pitch guage.

At some point in the early or mid eighties, by 1984, Peugeot used English threads.
