Item Description

This very Musket was featured and test fired on an episode of History Channel's Pawn Stars in April 2024. You can watch it on the episode below:

Original Item: One of a Kind. This is a lovely example of a VERY scarce experimental early percussion musket design. During the late 1830s the British underwent trials of various experimental percussion designs to replace the venerable Brown Bess Musket. The eventual winner was an experimental back action enclosed hammer design presented by George Lovell, Store-keeper at Manufactory at Enfield. The design was inspired by the enclosed flint-lock of Henry Nock.

One of the other designs looked at during this time was this interesting mechanically primed percussion underhammer .75 caliber smoothbore musket, actually based on a design by a French Urologist, Baron Charles Louis Stanislaus Heurteloup. This design was based on a primer described as 'a small pipe or tube made of soft metal or other substance which may be easily divided, containing the priming', and patents were secured in France and in England. The first example of this utilized a standard side action lock design, with these primers stored in the butt of the gun. This was then changed to an underhammer design to avoid possibly infringing on a previous patent, and the primer storage moved into the fore stock in front of the hammer. It was this "Koptipeur" design that was presented to the British Board of ordnance for trials, where it was rejected. It was however accepted and used to some extent in France and Belgium.

Fewer than 100 of these muskets were made, and this example bears the "Opposed Broad Arrows" British Board of Ordnance “sold out of service” markings on the right side of the butt stock and on the left side by the lock. There is also the number 113 stamped on the right side of the butt stock by the butt plate. The left side of barrel also has an  ЯR / Broad Arrow marking. As with most trials rifles, there are no other markings present on the gun at all.

A lovely example of an extremely scarce experimental ignition system that was definitely ahead of its time. Ready to add to your collection!
