A friend of mine just dropped off a gun for me to work on that came to him from his dad. He just wants me to clean it up and make it functional again. nothing major. But its sat in the corner of a closet for time untold. I would like to have a little history of the rig when i hand it back to him. OK barrel stamps are: Iver Johnson TRAILBLAZER Lakefield Jacksonville, AR Cal 22LR Arms-CAN Any and all info/history would be appreciated.
