I just added my first Ballard to my single shot collection and would like some info on it. It is a 3 line JM MARLIN NEW HAVEN but the R is replaced with "P" PAT Feb 9, 1875 and below "BALLARD'S PATENT Nov 5 1861" it is a ring lever falling block 22 lr with a heavy octagon bbl. serial # 1594 Any info appreciated. I can't get photos loaded.
