I had a nice, 60’s Atala bicycle, the tubes and fork were Columbus, it had Campagnolo dropouts, chrome lugs, and old Campagnolo components, the paint was a wonderful, multicoated candy apple red. The seat stays where they attach to the frame were different on my bike than on yours, otherwise it looked the same. Honestly, I would rather have your frame, I prefer the ride quality of 531 to Columbus Rinforzati.
