Fuji Touring Series IV had a similar brake cable stop bridge, when they didn't have cable hangers from the seatpost bolt... I don't know about the rack mounts in back, though; they might have been added later. The points on the front of the headtube lugs look similar on the Fuji. But the Univega Metroprix sure does have exactly the same bridges on back. My vote would be Metroprix with rack mounting barrels added later.
