First measure your actual shell width. Is it 70mm? Under the DS Cup, is that a spacer I see before me?

It’s not a groove as to denote a left hand thread?
Should have remembered we are discussing an Italian bb, no left hand threads around.
I think you were on the right track, because GXP bearings are handed, but Italian threads aren't, it's useful to have the drive side cup clearly identified.
