As you can see, the cups and locknut are steel. The top cup, rather than being hexagonal, has flats cut into it. Doesn't match the pics in either the '68 or '74 Campy catalog, Pista or Road.

What have I got here?

Nuovo Gran Sport. from the second half of the 70's

now how the heck did that get in there?

Also Triomphe, until '86. The Triomphe S3 group used the Victory headset.
