The only thing Miami Jim didn't mention is the brake nuts. Old bikes had brakes with a long bolt and a nut on the other side of the bridge or crown. New bikes have a short bolt and a long nut that fits into a recess on the bridge and crown.

If it were me .... I'd find a classic in the late 80s-early 90s range. Your short reach brakes will probably fit, at the least the frame will have the recess for the nut so you can use modern brakes. The frame will probably be 130 already and if a lower end, 7s model it'll be 126 and easily spread or cold set.

If you want to keep your bottom bracket (and why not) go with whichever you already have, British or Italian.
