NRA Museums senior curator Doug Wicklund shows us the world of William Walker Marston, a small New York gun maker active from the 1850s until his death in 1872. He's known for his single-shot breech loaders using a leather cartridge. The inexpensive alternative could be reloaded, but held only about 10 grains of powder. It had little stopping power, more likely to bounce off its target than to penetrate. Inexplicably, it was known for years as a secondary martial pistol. Marston also made a three-shot pistol, with three dialable barrels and a knife!
