This is a 4 shot reproduction Pepperbox revolver made by CMC, serial number 2442P. I think it was manufactured in the 80's.
It's .36 caliber, was only fired a couple of times, and it's been sitting on my desk for the last ten years. I hate cleaning these things, so I'm not going to shoot it.
It takes #11 caps, and I shot it with 36 cal (.350") round balls, 20 grains of FFFg, and 36 cal revolver wads. It went "BANG" 4 times, hilarity ensued, and a good time was had by all (until I had to clean it).
It's a double-action (trigger cocks and drops the hammer) but you have to manually rotate the cylinder. The trigger deactivates after you shoot it until you rotate the cylinder.
Give me $200 cash or Venmo at my shop in Littleton and it's yours (if you use plastic, the price is $206). I'll ship it if you want for actual cost (no FFL required).
