Manufactured as part of a contract held by Henry Deringer of pocket pistol fame. He manufactured 13,000 of these rifles in multiple variations between 1817 and the early 1840s. These arms are among the first widely issued rifled firearms used by any military and saw use into the Civil War era. This example has a lock plate marked "US/H. DERINGER/PHILADA". During its time of use the barrel and forearm were shortened and a brass blade front sight added. The barrel is marked "H. DERINGER/PHILADA" on behind the fixed notched rear sight and a defaced "V" proof along with clear "P/US" on the upper left flat at the breech. The buttstock has a patch box containing a worm and "U" shaped screwdriver. With a leather sling. Provenance: The George Moller Collection
