Yes, you are correct. The revolver is a cylinder fired handgun that was invented by Sam Colt. He got the idea from his sailing days. The ships wheel became the cylinder for his revolver. I believe the first one he invented was the 1836 patterson (built in New Jersey) revolver. If you had one, it would be worth a mint.
