These bellows air guns were generally made in the late 1700s to mid-1800s and were used primarily for indoor target shooting. Their basic feature is a conical bellows hidden in the hollowed-out wooden buttstock. "K. KIENDLBACHER" sliver inlaid on top of the tip-up octagon barrel chambered in approximately .34 caliber/8.5 mm (possibly for use with 8 mm darts with a hair tail) with a smooth bore that loads from the breech and releases with a lever that protrudes through the bottom of the stock ahead of the trigger guard. Absent tang peep sight. Loose pin included separately. Includes crank handle. Mechanically untested. Circular brass collection tag marked "R.D. BEEMAN/PRIVATE/COLLECTION/647" hanging from the trigger guard. Information on Bellows air guns can be found on pages 213-214 of "Blue Book of Airguns, Thirteenth Edition".
