Interesting Campagnolo Pista Headset: ID?

[Bike Recyclery]

Ok Campy experts...identify this headset! No cup markings on the outside or on the flanges that fits in the headtube. Made in italy and British threads markings inside cup and on locknut. Appears similar to a Record Pista, but those still should have markings on the flanges. It may just be me, but the cups appear more "dome" shaped than a usual Campy HS.

Any ideas? Thanks!

Spoke too soon. I just ID'd it as a Triomphe/Victory Pista. Seems doubtful, but is there a difference between a Triomphe and Victory pista headset? I don't even see evidence of one made as a Victory, but ya never know.

Re:

Never heard of Victory or Triomphe pista. As far as I know the only pista (track) group is the Record.

This headset looks to me like a Campagnolo Gran Sport.

Re:

more research proves it's a Triomphe strada. You're right, no pista strada.

Looks like standard Triomphe kit to me. Sturdy and basic.

VeloBase can be hazy but seems to nail this one quite well - http://www.velobase.com/ViewComponent.a ... &AbsPos=29
