Many year ago I bought a neat pistol at a gun show, thinking it was a standard percussion ignition system. When I got it home an inspected it more closely I found I had a very unusual gun. I've slowly worked out how the system works, but have yet to identify the pistol, maker, country of origin, etc. Maybe some here would like a look.
A closer look at the cock shows it has a rearward extension, a sort of dog, I guess, sharp as a knife edge. That dog interacts with two "sears" of very similar shape which protrude through two holes in the lock plate. Here are photos of the cock in the fired, half-cock and full-cock position.
A look at the very unusual internals of the lock.
Describing the action so it is understandable is difficult without the lock in hand. Basically there are two block, right and left. The right block is fastened tightly to the lock plate. Fastened to the top of that is a thin sheet of spring steel which extends over and is fastened to the top of the left block. The left block is free to move with the spring steel sheet, and lifts off the lock plate when the spring is flexed. Pressure of the trigger on the arm extending from the spring sheet raise the end of it and the left block. Two "sears" are fastened to the left block and extend through the lock plate. As the left block raises and lowers the sears extend through and withdraw from the lock plate and contact with the dog on the cock extension.
This is where the phrase "clear as mud" originated.
The trigger is light, smooth and fully controllable, a delight to feel. I don't know who worked this all out, but they did an excellent job. The pistol fits my hand as any pistol should, is a natural pointer with no effort. I've never fired it, but I am sure it would be an accurate one.
