That HS arrangement was common on Swiss bikes. I have a 1968 Allegro Special with the same dimensions. Makes one a bit nervous about the wall thickness of the steerer. Also, some French top nuts don't have clearance for a 22.2 stem.
Anyone know how a Swiss Stronglight Competition fixed cup is marked? This does not have the ring code, but is marked "Stronglight France 35 x 1". I think Campy Swiss cups are marked 35 x 1 G, the "G" being Gauche, French for left, meaning left-hand thread. I guess the Swiss BB's must have been made in Campy's factory in France.
