Here is a really nice antique Chocktow, Oklahoma & Gulf Railway brass Adams & Westlake Company switch key. It is stamped in block letters "CO&GRy", and on the reverse side it is stamped "A810, S", manufactured by A&W in oval hallmark. The key has dark patina and shows very little use, excellent condition. It measures 2 1/8" long, and the hilt is 7/8" wide. These keys from this railroad are getting harder and harder to find, so don't miss out!
