Hi, I have a friend is selling his dad's old Browning .308 BLR rifle (Belgium). I think it was made in 1972. It was left in a basement and has suffered some rust and pitting on the barrel. He sanded off most of the rust, and took a lot of the blueing off with it (from the barrel and most of the receiver). Photos below What would a fair price be for this rifle? As is. Appreciate your input. David PS - Comes with a few boxes of 20 rounds imperial ammo with a price tags on them of $6.00 (Canadian).
