Not sure if it was the same, but there was windup ones that used a cap from a "cap gun" and a winding mechanism.
You'd wind it up and the pin stopped it from acting.
Pull the pin and the gears would unwind, ending in a strike to the cap.
It's possible there was acoustic properties inside that amplified the sound, but more likely it just sounded like a cap gun.
The ad mentions a cap and a 4sec delay, so I imagine this is something much the same as that.
