A block of wood that a hammer rests on is typically called a hammer block or a hammer rest. It is used to support the hammer in a stable position when not in use.

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.
The main difference between a single action revolver and a double action revolver lies in the mechanism of firing. In a single action revolver, the shooter must manually cock the hammer before each shot, which also rotates the cylinder to align the next round. In contrast, a double action revolver allows the shooter to either pull the trigger to both cock the hammer and release it, or manually cock the hammer for a lighter trigger pull. This makes double action revolvers generally faster to fire in succession.
