S&W wartime revolver?

[Brian Dick]

I have its twin, serial number 688554. It has a British style lanyard ring instead of the S&W/Colt type on yours. I thought the small proof in front of the trigger guard on the left side of yours and behind the trigger guard on mine are British military but could be wrong. My guess is they were all prewar purchase prior to Lend lease and used in WW2. There were 110,379 purchased by the British starting around sn. 680000 according to the 39th edition, Blue Book of Gun Values

I also have two of the 5" LL revolvers, one with a Canadian ownership mark and the other an Australian owned revolver that's Parkerized with post WW2 Aussie FTR markings.
