Thank you. Yes #12496. It's a 4th variation British Svc Revolver in the database I sent. And since it has British military marks, see the final quote below:


4. “.44 HE - 1st Model”, ‘Triple Lock’, same as #1. above, but not likely converted .44s, just assembled into .455s:

“As the Brit contracts were finishing up in April, 1916, [H of S&W pg. 203] S&W found enough [HE 1st Model TL frames, possibly already numbered as .44s, and .455 barrels and cyls] to build 691 .44 HE 1st Model [per Roy Jinks in various letters] Triple Lock frames [for chambering in .455* like #1. above]. These guns are numbered in the .44 Spl serial number series. I have no idea why they were not just numbered in the .455 series. Perhaps it was .455 barrels and cylinders that the factory found, and they simply turned again to existing 44 HE 1st Model TL frames to use them up. They were sold commercially.” Lee Jarrett

11/3/15 “In April, 1916, the Factory found enough parts to assemble 691 Triple Lock 455s. They were assembled from April to Oct of 1916. They were numbered [late] in the 44 HE series. All I have seen are numbered from the 12,000 to 14,000's. [in 1916 and 1917 - 325 were sold to Shapleigh Hardware Co. and some to Simmons Hardware Co., St. Louis, MO.]
Some letter as being commercial sales, but I have long suspected that S&W simply slid many into the last of the British shipments at the standard price for the 455-2nd Models. I say that because I have observed several now with Brit ordnance marks and/or commercial proofs.” Lee Jarrett
