Interesting gun. It was shipped early Jan 1941. Where to will require a factory letter. I could have been a British purchase, either by the British Gov't Agent or a british dealer in Britain, as they were buying what ever S&W had available, or it could have been a private purchase by a citizen who then donated it to the " Donate a Gun for Britain" programs under way at the time. I obviously made it's way into British Military or Home Guard use judging from the multiple stampings, These proof stamps were reqired for commercial guns at the time, but as the war drew on they were dropped for military purchased guns and not applied until the guns were later sold as surplus and marketed in Britiain for commercial uses. An inquiry, with a photo, to the Imperial War Museum in London may get a reply telling you what the unit mark represented. Ed.
Yes, the 5" Victories had a special, and now very scarce, 5" USGI holster designed and manufactured for it. These were made by Boyt Saddlery and were all dated 1943. The photo below illustrates the example in my collection as compared to the similar holster designed for the 4" guns.
The pics from the first poster above have now disappeared so regrettably I can not see them.
