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. "F:HOVER .IN GMUNDEN" marked on top of the tip-up octagon barrel chambered in approximately .28 caliber/7 mm (possibly for use with 6.5 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, absent/broken hair trigger. Information on Bellows air guns can be found on pages 213-214 of "Blue Book of Airguns, Thirteenth Edition". Provenance: The Dr. Robert D.
