A rare piece of British manufacture, the 2.75 in. Whitworth Rifle was designed to be loaded through the breech.
The Whitworth also used a unique projectile and rifling system.
Whereas most rifled cannon of the period used projectiles with an expanding base plate that caught in a series of lands and grooves,
the Whitworth featured a twisting hexagonal bore and used a special hexagonal projectile.
The result of this extremely efficient design was a range of 2,800 yards and a distinctive high-pitched shreak.
Unfortunately, the breechloading mechanism was prone to jamming and the weapon was frequently converted into a muzzleloader.
The Whitworth Rifle was used in extremely limited numbers by both sides during the war.
The Whitworth Rifle was designed by Sir Joseph Whitworth and was manufactured in Manchester, England.
