Few years back I picked up like new 16ga Model 31 with alloy frame. The gun was made in late 1940s. Recently LGS had 20ga Remington 11 that looked like it just came out of the box. We live in a country that has seen no turmoil or chaos of war guns like what you show are more common then sellers want us to think. Frankly the biggest danger to many of those guns are humid walk in closets of the Deep South.
