German Striker for Gas

Period German striker mechanism for lighting things like gas stoves or torches. It seems to work, but the flint that is in it needs replaced. I am not sure if it would work after that or not. The mechanism seems a touch slow; that could just bee the old flint being sort of gummy and slowing the striker wheel down. Some rust. Once you depress the button, it catches at the bottom so you have to pull the other little lever back a bit to release the striker button. It has a maker mark, but I am unfamiliar with the company.
