I have a Rohn .22 LR revolver. It looks like a single action but it shoots double and single. I think the Blue Book of gun values says it "has no real value". How's that for cheap?
I got it from my father in law before he passed on (along with all of his other guns). It fires. But it has been relegated to quick-draw and trick pistol practice 'cause I don't care if it hits the floor and it is about the right weight and balance for that sort of fooling around.
I have never to date sold any of the guns I have, except for one that I found. I sold that Sears Roebuck bolt action (I think it was a Stevens) 12 gauge shotty to the City of San Francisco in one of their gun buybacks for $200. It was worthless to me until that day.
