The two Moto becanes I've had were either Swiss thread or Japanese thread. Both have the fixed cup threaded the proper way, not the French way. Just my 2 anecdotal cents.
Every Continental I've ever flipped had a bent rear axle, every british 3 speed I've ever flipped had a bent front axle and I don't think I've ever had a bike that didn't need at least a little fork alignment work.
Yes, it's a new challenge every day.
