After searching. Looks like this is a 96/97 Campagnolo Mirage short cage rear derailleur.Designed and intended to be run 8 speed with a Double crankset . Why on earth is this on my bike build with triple Specialites crankset and 7 speed shimano freewheel, 8 speed Campy brifter, is anyones guess. We shall find out whether that is compatible.
