Probably made in America, it's essentially a multitool of death, offering a small dagger, brass knuckles, and a single-shot pistol. That's it. If you need to open a bottle of wine or pick your teeth, try Switzerland.
The model you see here, serial #219, sold at auction for $5,000 in 2014. The auction house theorizes that this was "an early developmental or prototype model" and notes that "the absence of proof house or import marks…suggest American manufacture."
An earlier version with the serial #150 also sold (price unknown) in 2014 at a different auction. Interestingly, we can see that they started out by carving the product name into the brass by hand, which was surely more time-consuming and expensive than #219's stamp job.
