Even though the doubles you see here don’t look related, they share a feature that makes them cousins, or maybe even step brothers.
This feature is the rotary-fastening top bolt. The rotary-fastening top bolt was invented by Alexander T. Brown in 1883. A year later it found its first use on the side-by-side shotguns made built by a company owned by Lyman Cornelius Smith. The guns built by A.H Fox used a similar rotary-fastening top bolt, although the rest of Ansley’s shotguns are much different.
I’ve always like L.C. Smiths. I think they’re just as nice as Foxes — especially LCs like the 16 gauge below.

This 20g Fox CE is a hard gun to find. Fox made just 413 C-grades in 20 gauge. The first one (CE #200,011) left the factory on September 17, 1912 . This one was built 11 years later in 1923. While its price seems high, it’s not crazy. A minty, original one like this is worth $18,000+.
