This particular Chinese pistol is a great example of all the elements of a proper Chinese Mystery Pistol: sights that don't function, gibberish markings, mechanical derivation from the Browning 1900, aesthetic elements form the C96 Broomhandle Mauser, and clearly handmade parts. However, it is a particularly high quality example of the type.
