The Definition of Damascus Barrels
Barrel tubes built up by twisting alternate strips of iron and steel around a fixed rod (mandrel) and forge-welding them together in varying combinations
according to the intended quality and the skill of the maker. The rod was withdrawn, the interior reamed and the exterior filed until the finished tube was achieved.
Damascus barrels may be recognized by any of a variety of twist or spiral patterns visible in the surface of the steel.
Before the 20th century, barrels were typically built in this manner because gunmakers did not have the technology to drill
a deep hole the full length of a bar of steel without coming out the side.

A needle gun is a bolt-action firearm (the first known type of bolt action rifle) that has a needle-like firing pin, which can pass through fully self-contained (paper) cartridge case to strike a percussion cap at the bullet base.
The first experimental needle gun was designed by Jean Samuel Pauly, a Swiss gunsmith, in 1812.
