By WWII England had gone to the Enfield Top Break in 38-200 (38 S&W). I had a WWI Webley that had been "Cut" (milled) to use 45 ACP on 1/2 Moon clips.
Any S&W No 3 Schofield guns were 65+ years old and made for Black Powder loads with lead bullets, so they wouldn't be issued to any Military, but some civilians might still have some.
The old Single Action Army and Colt New Service & 1909's had 45 Colt Chambers, but the 1909 AMMO was a Schofield length case with a Colt rim diameter. I have samples with both lead or jacketed bullets in my collection, and pretty much 45 ACP ballistics. All the M&H guns in 45 were 45 Colt Chambered, never heard of any chambered in 450/455, like the S&W Triple Locks were.
Most of the large bore Irish and Continental revolvers in centerfire were in a 44-caliber similar to 44 Russian. Every country had their own name and loading but it was surprising how many were actually interchangeable. (except for Montenegro, theirs was bigger than a 45 Colt!) Plus, there were between 3/4 and well over 1 million actual, licensed, and unlicensed copies of the No 3 in 44 Russian. (Before the 1911 The No 3 was the most manufactured handgun in the world! Accurate quantities from Belgium and Russia have never been established.)
