I'd be willing to buy or trade for these if anyone has some they're willing to part with. Either British or French thread is fine by me.
I have two sets of 170mm Pro 5 Vis crankarms to offer in trade. One set is NOS, with some shop wear and British threads. The other is in very good used condition with French pedal threads. I can retap these to British if desired.
