Nuovo Record, most likely. If you have a braze on FD bracket I have one in nearly new condition for sale (also have a NR bottom bracket, but it is Italian threaded, and 52/42 crankset). You may be able to find a good deal on Campy levers and calipers on Craigslist or ebay, otherwise (if you don't mind going out of the European theme, think about a Diacomp Royal Gran Comp brakeset, which can probably be had for less but cosmetically and functionally is really nice. Suntour Superbe is also great and period correct, but will probably cost even more than the Campy's. Definitely stay with sidepulls. Bars could be Cinelli or 3TTT, ITM- what is the diameter of your stem?
