Count me in here is the picture of my Spiller & Burr, I just recently found the serial # on the base of the grip it's Bxxxx with a 4 digit number. the arm has been reblued and I believe they removed the proof marks of the weapon, I do have a fellow active police detective that may be able to bring up the proof marks. (carbon something or other). Any way count me in, I bought it at a pawn shop about 5-6 years ago for $100.00, and it came with 100 balls, and a tin of caps. Thought at first I got ripped off until I shot that puppy, man it's accurate. Sorry fellas and gals, I can't get the thing to show my pics, it says they've allready been displayed on "Need advice on first black powder revovers, have my eye on a uberti 1861 navy". I don't understand this function.
