I am relatively new to the air gun world. A while back I picked up a Beeman R1 in a trade. I knew nothing about the Beeman, but it's heft, fit and finish, and overall quality, made me feel confident that I was getting the better end of the trade. Recently, I was trying to do some research to determine the value of this air gun. As I mentioned, it's a Beeman R1. It is in 20 caliber. But, every other Beemen I have tried to compare it to have a nice blued finish. Mine has a flat black textured finish. I have no reason to believe that it did not come from the manufacturer this way. But, in my limited experience, I have never seen another one like it.Any information or advice you can offer would be greatly appreciated.
