Snaphaunce action

A few years after the introduction of the wheel lock, a simplified design combined flint firing from the wheel lock with the simplicity of the spring-actuated matchlock. Nearly every industrialized nation in Western Europe claimed its invention. The snaphaunce shared the side-mounted powder pan of later match locks and wheel locks. It used the basic spring cock and replaced the match holder with a flint holder. To provide a sparking surface for the flint, designers fitted a steel striking plate (anvil) that pivoted over the side pan. When the cock fell against the anvil’s curved inner surface, it pushed the hinged anvil up and created a shower of sparks downward into the pan. For little more than the expense of fabricating a spring matchlock, nations could arm their troops with a simple, flint-fired musket or pistol.
