Looks like a "parts bike" to me.

The headbadge is late '80s ~ early '90s.
Around that time, Pinarello started using "Pinarello" dropouts, rather than Campy.
I've never seen a Pinarello from that era with the cable stay on the rear dropout like that.
The Campy Nuovo Record stuff; the bar that I've never heard of, the Guerciotti seatpost; and the brakes are telling me that someone bought the frame and put whatever components they had on hand on it.

If it were mine, I'd look for some period correct Campy Record/Chorus/Athena parts and convert it all to that. Or even some Dura Ace from that time frame (I know...the purists will cringe, but there were plenty of Italian framesets in that era running DA).
