I have always had a fancy for ASM revolvers. I am curious about yours: what is the date code?
Later ASM revolvers (70's and onward) concentrated the date code, proof marks, serial number in a small area on the bottom front of the frame near the barrel lug.
This is a photo of an ASM 1849 Pocket, but it is the same as the other ASM revolvers insofar as the nomenclature is concerned. The left arrow points to the ASM logo. The right arrow points to a two letter date code in a rectangle. The other markings are two proof marks and the SN.
