All CW Union swords are very well marked. Makers marks, Inspectors Marks, State Marks etc. But Confederate swords are a whole different ball of wax. Most of the CS swords that are marked such as the Nashville Plow Works, Boyle & Gamble, Cook Brother etc are well know. Most others fall into that black hole of "Dog River" or "Cornpone" There were many small foundries and Blacksmith shops that made swords, d-guards and other items for the Confederacy and were never marked. When Bill Albaugh wrote both his CS Sword books this sword was not included. Even Howard Crouch's book also fails to Id this one. Over the years swords would come out of the woodwork with markings that would help Id other swords. Here is one that falls into that category. I bought this one over 35 years ago (for almost nothing) as a Dog River and knew it was CS with the unstopped fuller, crude castings etc. A few years ago a sword came out of an attic with the same features, mushroom pommel cap, big bulge in the grip, same crude casting channels and distinctive blade. The only difference in this one and mine was it was marked on the blade. B Douglas Columbia SC and now mine is not a Dog River anymore. This is the one found in the attic and marked. And here is my B Douglas formerly know as a "Dog River"
