I need some help with this some information on this rifle. This rifle was originally purchased by my grandfather on December 31, 1962. I have the original paperwork from his purchase. He passed away several years ago and my father and I have decided to sell the gun because it is just too much rifle for either of us and we feel it should go to someone that can appreciate it more than either of us. My grandfather used this rifle on his African safari in 1964 to shoot a bull elephant, a bull eland, and a cape water buffalo. This is a Belgium Browning Safari grade 458. The serial number on the gun is L4066. I am trying to find out any and all information about this rifle. I have tried to do some research myself but there is not a lot of information out there. I am also trying to at least get an estimated range of value. Any and all help would be appreciated.
