I usually refrain from giving British gun information. It’s a bit outside my field, and the inquirer (after getting info, of course) usually can’t resist a snarky parting shot about how unfortunate it is for one to know entirely too much about firearms or sling some other "gun-nut" mud.
However, Ohio is somewhat west of downtown London.
Colt revolvers actually sold in England before gaining popularity in the US. Colt’s London Model 1849 Pocket Revolver was small in both five and six shot .31 single-action percussion models.
A Colt cartridge New Line Revolver was in .32 rimfire manufactured 1873-1884. The trigger was encased in a spur jutting below and had no trigger guard. It was a small single-action quite popular in the UK.
In 1876-77, Smith & Wesson made a .38 centerfire pocket revolver called the single action 1st model. As the three sibgle-action revolvers above, it had the sheathed trigger with no trigger guard.
I agree with SMCC. The Webley Bulldog was made in the late 1870s. It was a double-action five-shot in .32, .44, and .45. It was small, snub-nosed, had a large trigger guard, and was quite popular in the UK as a pocket revolver well into the 1900s.
The Walther PPK didn't come out until 1931, but then James Bond is timeless.
Hope some of this helps.
