Very rare Prussian breech-loading percussion carbine. This carbine was used by the 2nd (1st Pomeranian) Grenadiers “King Frederick William IV". The overall length is 36". The barrel is 19⅞". The caliber is approximately 13.6mm (.535"). The bore is excellent. The bright metal is excellent. The stock is excellent. Barrel on the left, at the breech, has serial number “842". This is repeated (842 or 42) on many of the parts. The barrel has a crown over “IR" (JR?) at the top next to the bolster. The lock is marked “SP.&SR./SUHL". This is shorthand for Spand Gerberg & Sauer, Suhl. Germany. The right side of the butt stock is stamped with a crown over “FW" (Fredrick William). The butt plate toe is marked “2G RE/ 3 165". There is a trap in the butt. The stock has a nicely formed cheek rest on the left. Left side of the stock also has a 5" sling bar and ring. The action is unusual. First, there is a rotating spring-loaded nipple protector/ safety, second, the breech is opened by first rotating the nipple protectorr/ safety forward, then releasing the hammer so it rests on the nipple, then pulling up on the bolt tab until it rotates to vertical, then rotates approximately 30° to the right, and finally pull the bolt to the rear to load the chamber. Repeat in reverse to prepare for firing. It’s not too hard once you’ve done it a few times! The action functions correctly. This is the only one we have seen in the last 45 years. Probably only enough were made for the 2nd Grenadiers and its by Sauer as well!
