1851 navy unknown maker

[JQuigley]

Hello,
Just trying to figure out the maker of this 1851 I got off here not long ago. Appears to have been nickel plated at some point and stripped. Says made in Italy but nothing more aside from the black powder only and has some proofs. Nothing under the barrel behind the lever either. I have the original short barrel but swapped it for a Pietta. Thanks!

Armi Sport?

I was thinking ASM for some reason. I know nothing of the stampings

None of the markings match my ASM.

What makes you think it was nickel plated?

What makes you think it was nickel plated?

Around the recoil shield and on the underside above the serial stamping as well as other tight corners, there were remnants of what appeared to be nickel over what appeared to be copper(need copper to adhere nickel to steel). You can see if you look closely in the pictures on the bottom of the shield and on the serial.

The letters PN stamped on these apparently are meaning black powder only, or that the barrels or the gun has been proof tested for black powder, you find this stamped on a lot of percussion revolvers but I don't believe I've ever seen it on a metallic cartridge black powder revolver.

This is the year chart of the year code numbers apparently these are on everybody's from ASM to pietta

The BM is the Italian date code for the year it was proofed, 1999 in this case.
PN is the Italian abbreviation for Pulvere Nero or black powder.
The shield stamp signifies that the pistol was proofed at Gardone, Italy.
