Duration: 21:13

This video details the unique operation and mechanics of a mid-19th century turret revolver, specifically a Heinrich Genhart design. It highlights the complex system involving a reciprocating barrel for gas sealing and an underhammer mechanism for ignition. The presentation emphasizes the intricate loading process for its custom cartridges and the reasons behind its limited production and eventual obsolescence.

Quick Summary

The Genhart turret revolver is a unique 10-shot firearm featuring a vertically rotating cylinder and a reciprocating barrel for gas sealing. It utilized a complex underhammer ignition system with custom metallic cartridges employing Manton's tube percussion primers, making it an innovative but ultimately impractical design.

Frequently Asked Questions

What makes the Genhart turret revolver unique compared to other revolvers of its era?

The Genhart turret revolver is unique due to its vertically rotating 10-shot cylinder and its reciprocating barrel system. The barrel moves forward to allow cylinder rotation and then rearward to create a gas seal with the chamber, a feature patented to enhance efficiency and prevent gas leakage.

How did the Genhart turret revolver handle ammunition, and what was its ignition system?

This revolver used custom, self-contained metallic cartridges with a protruding primer at the rear. Ignition was achieved via an internal underhammer that struck upwards into pockets on the cylinder's base, utilizing a form of Manton's tube percussion system with copper primer tubes.

What were the main reasons the Genhart turret revolver did not become widely adopted?

The primary reasons for its limited success were the complexity and impracticality of its custom cartridge system, which required users to assemble their own ammunition. The underhammer mechanism also presented challenges for integration with more modern cartridge designs, making simpler systems more appealing.

What historical trials did the Genhart turret revolver undergo?

The firearm underwent trials in Britain with the Board of Ordnance, where it fired 200 rounds rapidly, causing the wooden stock to smoke. Captain Minié also advised the French government against adopting the rifle version, though a small quantity was reportedly ordered.
