I have the one that belonged to my father-in-law. It was one of his favorites and the handgun he'd had the longest. It has both cylinders and is in the original box, but the box isn't in the greatest shape in the world.
It's a nice little gun. My mother-in-law used to have a bag of coins by father-in-law had shot holes in. He'd toss them up in the air, pull the gun from the holster and shoot the coins. He was very good shooting from the hip with that little gun. One evening we were out shooting (me with my Ruger Single Six and him with the Colt) when if finally got too dark to see the sights. We turned to walk back to the house when he stopped and said he'd found one more bullet in his pocket. He loaded in in the Colt cylinder, spun the cylinder around to put that cartridge in the right spot to move under the hammer when he cocked it and shot a soft drink can off the post even though we could no longer see the sights (we'd laid the cans on their sides when it started getting dark so we could see the shiny bottoms easier than the painted sides).
No idea what they are worth these days but I'll be passing his guns on to his grand children if I can get them together to take turns picking through them (handguns, deer rifles, squirrel guns and one shot gun).
They are 4/5's scale copies of the Colt SAA centerfire guns, if I recall correctly. Same action/function.
My father-in-law said he cash his check, stop at the hardware store and buy a brick of .22 ammo on Friday and by Sunday the brick would be gone. The next weekend he'd repeat it. No telling how many rounds he put through that little revolver over the years.
