I also have a track hub (a rear) that looks identical to the one on e-bay, with no stamping on the hub body and no colored bands like yours on the wooljersey site. I bought it as a sew-up wheel that had been built up on a Mavic 32h OR10 rim. The axle threading & lockring threading are the same as Campy. When I took it apart to replace the ball bearings, I thought I might see some markings on the axle - so such luck. Axle looks like a Campy axle however there is no keyed slot through the threaded area. The cone however is marked. On the flat end it's marked in all caps "CAMP," and also "10x26 SU" Ok, 10x26 is the threading, but what does "SU" mean? Also does CAMP mean Campagnolo? Of course the cone could have been replaced.
