Eugene, The gun, an english boxlock(name of retailer which I cant remember) is here in the states and is owned by a friend. I have not seen the gun as of yet but hoping to fix that next month. He took the gun to a well respected english trained smith who stated the gun was unfired since proof. Nitro proof 2 1/2" chambers 1 1/8oz load. The smith stated the gun could have failed proof for some reason and had to go through the proof house again. What would cause the gun to fail proof? So has anyone come across anything like this before? What does the reproof do to the value of the gun? Thanks, JB
