It can be a monumental task if there isn't a obvious makers name stamped. Many companies imported Flli Pietta, Uberti, Pedersoli and others under US store names often with no makers mark on the gun, same goes for the kit guns. Look on the side of the gun or under the barrel or under the lock plate for any clues. Other than that I would look to the on line auctions like gun broker or auction arms, and see if you can spot your gun in there listings.
I have provided a link that explains how to claen it in detail.

Yes.
Among other things, it COULD stand for Armi San Marcos- an Italian maker of reproduction black powder revolvers.
check in with ANTIQUEGUNLIST.COM and ask them who you can send pictures to in order to identify your pistol... also furnish details where pistol was found.
NO
Depends on the caliber. A .45 caliber pistol uses about 40 grains of black powder. Contact the maker's website and download the owner's manual for YOUR gun.
Either FFFg black powder or Pyrodex P may be used.

Yes, Black powder guns are extremley dangerous a licence is definitely needed
How much is a old black powder only 45 cal long barrel pistol worth?
First, find a copy of the owner's manual for YOUR pistol. Second, use ONLY black powder, or a modern black powder substitute, such as Pyrodex. The ROUGH rule of thumb is one half the bore diameter in grains of powder. A .32 cal would use ABOUT 12-16 grains of powder.
