I also own one (different model #), and my best estimate is that it was produced in the mid- to late-1970's.
Depends, A "Single Action" revolver, such as the Colt Peacemaker, carried in the old West, DID have to be cocked before each shot. A "Double Action" revolver, such as a current day Smith & Wesson, does not require that the hammer be cocked- it CAN be- or the trigger can be pulled, and the hammer will rise and fall.
