This video details the operation and internal mechanics of a Charles Lancaster 2-barrel pistol, designed by Henry Thorne. It covers the loading and firing sequence for both single and double-action style shots, highlighting the unique indexing mechanism that rotates the firing pin assembly. The presenter also explains the internal lockwork, including the linear hammer and its connection to the firing pins.

Quick Summary

The Charles Lancaster 2-barrel pistol operates in single-action, using the .476 Eley cartridge. Its unique indexing mechanism rotates the firing pin 90 degrees after each shot, allowing for sequential firing from its two barrels. Loading involves tipping the barrels, inserting cartridges, and closing them.

Frequently Asked Questions

What caliber does the Charles Lancaster 2-barrel pistol use?

The Charles Lancaster 2-barrel pistol uses a standard .476 Eley cartridge. This caliber was a precursor to the more commonly known .455 Webley cartridge, often found in large-frame revolvers of the era.

How is the Lancaster 2-barrel pistol loaded and fired?

To load, the barrels are tipped upwards, cartridges are inserted into each chamber, and the barrels are closed. It operates in single-action, requiring the hammer to be cocked before each shot. Pulling the trigger fires the first barrel, and the mechanism indexes for the second shot.

What is the unique mechanism of the Lancaster 2-barrel pistol?

The most interesting mechanical feature is its indexing system. After firing one barrel, the mechanism rotates 90 degrees to align the firing pin with the second barrel for sequential firing, controlled by cocking grooves and a guiding pin.

Can the Lancaster 2-barrel pistol be fired in double-action?

While it can be fired with both triggers pulled simultaneously for a double-action style shot, the firearm is mechanically a single-action pistol. This means the hammer must be manually cocked before each shot for proper operation.
