Are these small thread lines in the middle of the BB shell common?
The French BB has all right hand threads; they passed one threading tool through the whole bracket.
At some spot there seemed to be more wall t hickness and that left the marks.

Would it be at all possible that they changed the threading from BSE or ITA when they did this or is that completely impossible? I would think yes but I feel I should ask since I'm still trying to identify the frame as well and this could shed light away from it being more difinitively french if that's the case.
