BB threads - Peugeot / Motobecane

I know these folks used French thread in the early 70's - did either
one use Swiss threadings later on before going Japanese?

Thanks

Motobecane used Swiss threading sometimes. And it's BSC/ISO, not
Japanese.

I remember replacing the bottom bracket and crankset on my '78 or '79
Peugeot PX-10 and being told by the LBS that it had Swiss threads.

That's "Turning Japanese."

I really think so.

Peugeot was pretty much BSC by the mid (my '76 PX-10; wife's '77 UO-8)
1970's

Motobecane notoriously used Swiss threadings on their BBs, but earlier
models (um, sixties? early seventies? I have no idea) used French
threading.

So a '77 is likely Swiss ? Was there any way to tell French vs. Swiss
other than a wrench on the fixed cup ?

I don't know which eras had which BBs.

Not that I know of. I believe the canonical solution is to put the
wrench on the fixed cup, try one direction not too hard, then the other
direction a bit harder, then back again, a little harder, and so on.

Or, you could just leave the fixed cup alone,

Depending on the brand of cup, you may find an identifying mark of some
kind.
