I'm selling the rear derailleur off this bike, and someone asked whether it's short or long cage. I assume it's long. Is this correct?

There's no one definition for cage lengths, but yours appears to be a short cage. In Campy derailleurs short cage models typically are about 55mm on center between the pulleys, medium cages are 74mm.

My long cage '06 Chorus rd is 88 mm between pulley centers and my long cage Shimano Ultegra RD-6500 is 72mm. Campy made short, medium and long cages and Shimano only short (SS) and long (GS) cage road derailleurs.
