Showing this is deja vu but the various marking info may be of interest. I would like to know what each one means ----
A study in British revolver markings, my S&W Triple Lock Brit military, now .45 Colt. S/N 13XX, a 90+% gun but for a few dings from mishandling.
Marked right lower frame "Not English Made",
Left frame @ hammer Broad Arrow, Crown, FG, E, one over the other
Left frame at BC area, Crossed flags, Crown over circled V
Left Barrel above ejector, NP, Crown over circled GP, Crown over circled W -- ? not clear due over stamping
Seems to be a lack of consistency in British military revolver markings. I had a 2nd model S&W, with a lot more marks, each cylinder chamber, right barrel caliber & proofed X tons, etc.
