I take it this is not English Thread
I got a phone call from a friend who works at a community cycle center. They got a box of random parts including a campy six speed gear set. (I thought they were called cassettes but someone corrected me)
anyway, the box said “English Thread”
it never occurred to me that Italian parts could also be threaded for other countries. I am also under the assumption that if my record hubs were English threaded. They would say England instead of Italy. Amiright?

I've never tried to thread English to Italian or the other way around but I have read of others doing so

That assumes logic in the bike world. Not a safe assumption. Bike standards were all over the place until the '70s and '80s when the Japanese took the best of that was out there (with minor changes) and made that their standard. With their enormous market share (and insistence from mechanics that their shop carry those so-easy-to-deal-with brands, that standard became near universal for a few years. Now systems have changed and are changing and the standards mess is not a whole lot better than 50 years ago, just different.

And joking - this is an English thread! Every word of it. In fact, other countries are referenced by their English spellings. (I'm going for a ride. I clearly need it.)

Some day someone will explain to me the mish-mash of metric/fractional on bikes and how that came to be. 9/16” spindles thread into 170mm arms that ride on 1/4” bearings in a 68mm wide bottom bracket. Pick a unit of measurements and go with it!!

Per Sheldon: 'The older British and Italian standards use the same thread pitch but a very slightly different thread diameter, and are generally interchangeable. However, for strong riders and on tandems, it is best not to mix and match -- freewheels sometimes do strip the threads of aluminium hubs.'
I've used ISO freewheels on Italian-threaded hubs for a few years now without problems. I read somewhere (I don't remember where) that it's a bad idea to go back to an Italian-threaded freewheel, but since it's 2022 and I live in the US, I'm unlikely to want to that.

yes, but in this case the size stamping shown in the original post is for the thread type of the hub. Italian thread by an Italian company.
as opposed to English thread.
this hub was post CPSC by co-incidence.
prior one needed a Campagnolo decoder ring.
no groove - italian
one groove english
two grooves- French. ( most of the time unless it was plain)
Campagnolo dropped French hub threading as soon as practical.
the differences between Italian and English are primarily the inclusive angle of the individual thread, one at 60 degrees, the other at 55.
and I don't recall which is which, that is what Sutherland's is for.

Furlongs per fortnight would only serve to further confuse you.
