That is reasonable. Fit first.

If a RC from the 70's those bikes were made often for clients who could not afford full Campag. as the British called it back then. Weinmann 500 brakes, Campag. hubs (maybe even Tipos) and derailleurs, a Sugino crank even were more typical than full on Nuovo Record. I would build it up with Weinmann, Suntour, Sugino, a plain aluminum seat post, 3ttt bars and stem, maybe even a no name headset, Campagnolo Record high flange hubs, sprints. (British for Tubular tyres and rims, you have a commuter, so have a full on road bike)
