Beware, as I don't think the blue paint at the head lugs and seat lug is original. It could be hiding some sort of repairs.
If it has Supervitus 980 tubing, it could be a a PSN with a few components changed out. I believe it originally should have a Campy Victory crankset if it is indeed a PSN.
The PX10 from that era had similar paint and graphics, but had Reynolds 531 "Professional" tubing.
