...of note are the Campy NR derailleurs, and the Simplex retro-friction shifters. New re-laced wheels, on Campagnolo hubs, but they could as easily be the original Normandy Competitions, which are pretty nice hubs. I might have some lying around, and might build out some alternative wheels for this. Lively, light and compact in handling. Early 80's , or maybe '79 ?
