Editing Flintlock mechanism (section)

===Internal flintlock===
Weapons using internal flintlock are relatively rare. This variant of the lock does not have an external cock. Its function is similar to striker-fired guns. Instead of the striker there is a rod holding the flint. The pan is located on the upper side of the barrel. The pan has a hinged cover with grooves on the underside. The gunsmith Stanislav Patzelta is considered to be the inventor of this system. According to other sources this lock could have been invented by the Austrian gunsmith Karl Bischof (Carl Pischoff).
