Don't forget Mondia. The early/mid 70's are french threaded, although there is the occasional report of Swiss threading on BB. Very nice frames - mine has nervex pro lugs, reynolds 531 tubing, plenty of chroming, campy dropouts, pretty much the full monty all around, about as good as it gets for mass produced bike of that era (IMO). I was selling this, but since totalling my Tommasini, it has reverted back to keeper status.

Campy NR is super appropriate for Mondia, although they tended to come w/Mafac centerpull brakes.
