Manufactured from 1912 to 1935 this is an example of a Type III or Model 4 Derringer. The top of the barrel rib has the Remington-UMC address. It has a manual extractor and checkered grips. The barrels are numbered to the gun.

Excellent. The pistol retains 98% plus original matte blue finish with a few very light handling marks. The barrel latch and screw heads exhibit brilliant flashes of original fire niter blue finish. The grips are excellent with crisp checkering. Mechanically excellent. A magnificent example of a 4th model over/under derringer that would be nearly impossible to improve upon!
