This video explores the French M14 conversion, a modification of the Gras rifle to fire the 8mm Lebel cartridge during World War I. Faced with a shortage of Lebel rifles, France rebarreled surplus Gras rifles. The modification involved retaining the front portion of the Gras barrel and integrating a new 8mm Lebel barrel and rear sight. This allowed the use of existing Gras stocks and bayonets, and provided a means to redirect newly manufactured Lebel rifles to the front lines. The video highlights the historical context and the technical aspects of this wartime improvisation, while also noting potential safety concerns due to the Gras receiver's design for black powder pressures.
This video delves into the history and specifications of the Manville Gas Gun, a riot control tool developed in the 1930s. It highlights the various calibers produced (12ga, 25mm, 37mm), emphasizing that the 12ga variant was solely for tear gas and not high-pressure rounds. The description notes its intended use by prison guards and riot police due to its superior ammunition capacity compared to contemporary launchers. It also touches upon a WWII-era attempt to develop a high-pressure version for explosive rounds, which was unsuccessful, and the eventual destruction of the original tooling. The video also mentions the Manville company's wartime production of parts for Oerlikon 20mm AA guns.
