I recently aquired an Iver Johnson Arms & Cycle Works 5 shot hammerless revolver. Under the trigger is 1828, and under the grip is I 1828.. Additionally, I measured the barrel and it's 3 inches long from tip to cylinder. On the bottom of the butt, as near as I can tell, it says PAT NOV 1703, and PAT Pending under that.. Not 100% sure on the 1703 though, might be an "8" or a "6" at the end.. Anyone with any info on this, please help.. I think this is the gun my grandfather used as his second piece when he walked his beat. He was a straight arrow who ticketed his daughter, so I know it's not what's called a drop piece. If it's not his old piece, then someone left it in the house I grew up in.. Either way, I'd like whatever info I can get on it. From what I've managed to find out, it takes 32 cal short or regular rounds, but whether they are black powder or not, I don't know... And yes, I will consider selling it if I can figure out it's not my grandfathers..
