It's a Browning Hi-Power rifle.They made them in three grades-Safari,Medallion,Olympian.
Probably the best mass production sporting rifle ever made,period.I have a bunch of them.They are SCARY accurate,out of the box.
Just watch out for salt cured wood,and the occasional crack in the tang,and your golden.For salt wood,just pull the barreled action out of the stock and look for rust.If there is rust,run!!!!!!!
