Most famous for its use in the Dreyse rifle, this self-cocking revolver applies the needle-fire concept on a smaller scale. The cylinder is not completely bored through for loading from the breech and instead has a small hole in the rear face of each chamber. Loads from the front with paper cartridges. The needle extends through the hole puncturing the cartridge and striking an enclosed mercury primer which in turn ignites the powder charge. Blade and notch sights, "v. DREYSE SOMMERDA." on the top strap, "Cal: 0,35" on the right of the frame, light coverage factory engraving on side of the frame and trigger guard, matching serial numbers on the frame, cylinder, bolt housing, and grip, scroll engraving and silver wire inlays, checkered grip, and lanyard ring. Fitted with a contoured one-piece checkered grip with a lanyard ring on the butt.

Very fine, retains 75% plus original blue finish with some scattered moderate handling marks, scattered minor freckling, a mild cylinder drag line, and crisp markings and edges in the metal. Grip is fine with crisp checkering, a crack running through the left screw, and scattered light scratches and dings. Mechanically needs work, the action cycles although the needle is broken/absent and the sear mechanism does not function properly.
