I inherited a Browning BAR 22 Long Rifle from my father. It's from 1977, Grade 1 and in what I'd call very very good, to excellent condition. It's been fired only a few times, and in a gun case for the past 30 years. It's a nice rifle but I'd like to sell it, but don't really know what a fair price is. Can anyone give me a ballpark figure? Thanks.
