A heavy wall gun,
A so-called “double hook” (Dopplehacken), German. dated 1507.
Forged iron two-stage barrel in 1.5inch (40 mm) caliber with a heavily swamped muzzle. The rear third is octagonal then round after double serrations. Vent and pan insert on the right side. There are three square marks and the date "1507" stamped on the breech. The underside has two barrel lugs and a forge welded, perforated hook. Pitted surface. Length 57.25inch (145.5 cm).
This might be the second oldest dated firearm yet found. It is a type common in the 16th century as shown in the illustration below (ca. 1506). During it's working life it would have had a stock which would have been used more for aiming than to absorb recoil. For that purpose the hook would have been put over the edge of a wall.
This is an extreme rarity for the advanced collector.
