Among other things, it COULD stand for Armi San Marcos- an Italian maker of reproduction black powder revolvers.
It should be a #11 cap. Comes in tins of 100 available from CCI, Remington and many others.
If it is marked ASM (Armi San Marco) all I can be sure of is being made prior to 2000, when ASM was bought by American Western Arms. There may be a date code consisting of roman numerals or a pair of letters stamped on the receiver that would help, but it was not present on all guns.
I just picked one up in good condition for $140, I've seen them range from $120-$180 though. ASM parts are harder to come by because they went out of business. Uberti or Pietta would probably bring in a higher price. Still a good gun though.
The value of an ASM 44 caliber black powder revolver from 1843 can vary widely based on factors such as its condition, provenance, and any historical significance. Generally, these revolvers can range from a few hundred to several thousand dollars. To obtain a more accurate appraisal, it's advisable to consult a firearms expert or appraiser who specializes in antique firearms. Additionally, checking recent auction results can provide insight into current market trends.
I would need to know the exact model and the proof mark ( should be a series of Roman numerals like XXIV or a pair of letters AD, BL etc) other than that all I can tell is it was made prior to 2000 when Armi San Marco was bought by American Western Arms, and with the 4 digit # it would be an early 90's import.
