Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

Many Italian bikes are supplied with English BBs.

Meaning the right cup is LH thread. The safe way is to remove the left cup first since they're always RH thread, and use that to determine whether the BB is Italian or English, which will tell you which way the right cup will be threaded.

If you have a caliper, Italian cups are 36mm across the thread crests, while English are slightly smaller than 35mm.
