I can't tell if the second digit of the serial number is a 6 or an 8. If the latter, this gun is numbered very close to a couple of guns that went to South Africa in early 1940. The remnant of a lanyard loop and the smooth stocks say "military" to me. I must ask: is this gun chambered in .38 Special or .38 S&W? The Commonwealth contract revolvers of this period mostly chambered the shorter round, but some were produced in .38 Special.

If a military contract can be confirmed, most collectors would call this a British Service Revolver (BSR) or even a Pre-Victory.
