An Old World firearm that used the flintlock mechanism to propel bullets. A mechanism where a hammer holding flint strikes a piece of steel and produces sparks. The sparks fall into a pan of gunpowder and ignites the powder. A small hole from the pan to the barrel allows flame to travel and ignite the powder in the barrel. Replaced the matchlock and wheellock. This mechanism was eventually replaced by the more reliable cap-and-ball percussion system.
