The C model (for Camper) was a really short barrel 22 over 20 guage. It came with a case that fit the gun when it was broken down. Mine didn't have a choke either. I don't know why, I would have thought that it would have rated at least an improved cylinder. I didn't keep mine long, I couldn't hit squat with it, but I blame that mostly on the short barrels. It definitely was not a smooth swinger.
