edit: it's got the Carnielli 80 years sticker on it, so it's a 1989 or 1990.
I've got a rear hub that's basically worn out. It is a Gipiemme hub, 126 mm locknut-locknut width with a spin-on freewheel 6 speed cogset that is Campy GS. What I'm trying to do is determine if all GS freewheels were English thread, Italian Thread, mix of one or the other, etc. I could take it back to the bike shop and have them take it apart to tell me, but if I can find some knowledge here without doing that I'd prefer it. I don't own the special tool needed to disengage the splines so I can remove the cogset, so I'd have to have them do it. . .
