Hi.
I have a vintage campagnolo nuovo record hub with a freewheel sprockets assembled.
Is there any sign on the hub,or on the sprockets that could indicate the threading? without disassemble it.
Thanks in advance for any knowledge shared.

Campy hubs often have the threading stamped on either the hub shell right next to the threads (may be partially/fully covered by the FW) or the stamp is on the hub shell where it is absolutely covered by the FW...so you may have to remove the FW but if it's any consolation a French threaded Campy hub is pretty rare and the other 2 commonplace threadings (Italian and English as Campy calls it) are virtually interchangeable so 90% odds you can use a ISO/BSC/English FW and be fine.

The later hubs do have the threading stamped, the earlier hubs had a secret code.
No thin groove beyond the freewheel, Italian.
One Groove, English
Two grooves, French.

That code works for BB lock rings too, on them placed on the outside face.

here's a quick photo of a Campy Record hub shell, showing the markings that indicate English threading....

Hi I have checked,there is no any stamped mark nor groove on the shell of my hub. So it's presumably the earlier version hub of Italian threading.
Thanks a lot for the replies. I really appreciate.
