Brass Capper for Muskets
Brass Capper for Muskets. An unusual and rare brass capper for musket caps. Beautifully made but no makers mark. It has a sliding gate to allow you to fill the container.
The percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is a small amount of a shock-sensitive explosive material such as mercuric fulminate (discovered in 1800; it was the only practical detonator used from about 1850 to the early 20th century). The caplock mechanism consists of a hammer and a nipple, sometimes referred to as a cone. The nipple contains a tube which goes into the rearmost part of the gun barrel. The percussion cap is placed over the hollow metal nipple. Pulling the trigger releases the hammer, which strikes the percussion cap and detonates the mercury fulminate, which releases flames which travel through the hollow nipple to ignite the main powder charge. Percussion caps have been made in small sizes for pistols and larger sizes for rifles and muskets.
