Campagnolo Nuovo Tipo / Gran Sport low flange 40h rear hub with skewer, 120mm spacing, 1971. This is a rare 40 hole rear hub - for the extra strong rear wheel, meant for tandems, really really big strong guys, or those who just want to feel really really secure. The spacing is 120mm, which was normal at the time for bike with 5 or possibly 6 speed freewheels. When I got this, it had one broken lock nut.
On the inside of this lock nut it was marked "CAMP 71" which is the date code. I bought another Campagnolo lock nut, and it is the correct fit - but it turned out that it has a knurled (textured) surface, where the other original one does not see the eighth and ninth photos.
So a slight mismatch there, which I point out to you now, but which would almost never be noticed otherwise. The threading is not marked, but I test fitted a Regina freewheel that also fits nicely onto a hub that I have that is marked "England", so it is likely B. (British thread) but could be Italian. There is a scuff on the end of the quick release as seen in the next to last photo.The spoke holes look really nice - I don't know if this was built and used, but it certainly wasn't abused.
