E. Remington & Sons purchased machinery and a U.S. Navy contract for 1,000 Jenks carbines with Maynard tape primers from Ames Manufacturing Company and manufactured these carbines circa 1847-1848. A distinguishing feature of the Jenks-Remington is the Maynard tape primer on the lock. Marked "6/29" on the underside of the breech lever, "146" inside the primer door, this example has no markings on the barrel at the breech ahead of the oval loading port (does not appear to have ever had markings in that location), and a boxed script "RP" (Richard Paine) inspection cartouche stamped on the left of the stock opposite the lock. The oval loading opening found on many of these carbines was an alteration of the earlier round opening and was designed to facilitate the use of paper cartridge rather than loose balls and powder. The bore was also rifled at this time. The Jenks is unique in that it is the only side hammer weapon officially used by the U.S. military.

Very good, retains 30% original brown finish and strong patterns of case colors with scattered mild spotting/freckling and smooth gray and brown patina on the balance, bright golden patina on the brass, with sharp markings and edges in the metal. The stock is fine with scattered scratches and dents, a re-glued cracked section ahead of the lock, a few cracks ahead of the buttplate, and a crisp cartouche. Mechanically fine.
