Re: Ruger Blackhawk 357 mag
If the cylinder turns by opening the loading gate which is done without any half-cock of the hammer it's a New Model. Also very easily determined by it either having three screws or two pins. It does seem it's a New Model, but an early one if it doesn't have the warning. It will command a slight premium over a model with the warning but not alot unless it's complete (box, papers, etc) and in a favorable condition.
