Freccia valves were widely available as an aftermarket replacement (distributed I think by Causeway Autos/ Northwoods, and sold by the various A7 specialists) around 40 or 50 years ago, but have not been around as far as I know since then. There was nothing special about them, they were not oversize, and any standard A7 valve will do to replace them.
