Georg Priestel has published his work on "Jean Samuel Pauly, Henri Roux, and Successors - their inventions from 1812 to 1882 - New Light on the Forerunners of Modern Fire Arms Ammunition." This 74 page work should serve to explain the historical background and events of ammunition development with its inventors J. S. Pauly and Henri Roux, and to put these inventors in a better light than it had previously been. The author rewrites the early development of the Pauly and Roux cartridges. This composition of many individual pieces of a puzzle gives a picture of how the story went from the beginning to the modern central fire cartridge. It is available in PDF format and for free download via Research Press publications.
