One of less than 250 manufactured between 1955 and 1958. The Kimball was a failed attempt at producing a blowback pistol in 30 Carbine using a series of cut rings in the chamber. In theory, on ignition the casing would swell to fill these rings, delaying extraction long enough for pressure to drop. Of only about 238 manufactured, many were destroyed during use by the severe recoil, making examples in this kind of condition even rarer. Blade front and adjustable rear sights, with the Detroit address on the left side of the chamber, serial number on the right, and finely checkered plastic grips. The pistol is left "in the white" without a final polish or blue finish seen on the majority of Kimball pistols.

Fine. The pistol is in it's original "in the white" condition with dark patina throughout, rough machining marks, scratches and nicks, and some light pitting. The chamber marking is very faint. Grips are also fine with numerous small dings, and worn checkering. Mechanically fine. The magazine follower is absent.
