The only way I know to check for sure is to measure the threads. If you have a steady hand and a good ruler you can count the number of threads in the threaded area and compute threads per inch or thread pitch. English are 24 threads per inch. The Italian is I think very close to that, and I know the French is different. If you have a caliper that reads in thousands of an inch, measure the diameter of the threaded area. English will be 1.3750 inches, Italian will be 36.0 millimeters (divide by 25.4 exactly to convert to inches). I may not be right, but I think French has a 35 millimeter diameter.
Don't thread that lockring over it any more. The threads on the hub are delicate and not restorable if distorted. Kill the threads, kiss off the hub body, hunt on Ebay for another one.
Campy supplied hubs in whatever threading the bike company required. The only thing age or production year (not necessarily 1972, btw) had to do with it is in some years it was hard to see what thread you have.
