I am new here and this is my first post. I have several Rugers so I will likely be hanging around some. I have a few questions about a revolver I just acquired. It is a New Model Blackhawk, 41 magnum with 6.5" barrel. The serial number dates it to 1979. The guy I bought it from says he bought it new and it has never been fired. It looks to be in 100% condition, there is a slight ring around the cylinder from working the action and spinning the cylinder. I am wondering if there are any tale tale signs as to whether it has ever been fired. I wiped it down and there are no signs of any powder residue, just oiled it up and put it back in the box. Which is the next question. It is supposed to be in the original box, the box says Ruger New Model Blackhawk .357 Magnum on the end and has the proper serial number handwritten in white across the side of the box. Is that normal? did they use the same box for both calibers. And of course the final question, what do you think it is worth if it is unfired or if not.
