The Patents for Pauly Guns and Cartridges by Plomdeur, Cessier, and Delebourse

He was best known for his improvements to primers and percussion caps which he held a few patents on. In the 1830s he took out many advertisements for his improvements to guns and primers such as the following:

Le Charivari, 10 septembre 1837

There are two main areas that he addresses. First is how the hammer is connected to the plate, passing all the way through, which allowed for considerable fouling throughout the inside.

The Pinfire Page

The Pinfire Page was a recurring column I had in each issue of the bimonthly publication, The International Ammunition Journal. This compilation book combines together the first 5 years of my column, showcasing my research, images and other documents related to the pinfire system which was the first major breakthrough in modern ammunition.
