The Palmer carbine holds the distinction of being the first metallic cartridge bolt action firearm ever adopted by the U.S. Ordnance Department. The bolt does not contain a firing pin and is simply used to seat the cartridge and seal the breech. It fires with a traditional side lock. Approximately 1,001 of these carbines were ordered on contract by the U.S. government late in the Civil War, but they were delivered too late to see action. It has small "M.M" (Miles Moulton) inspection initials on the left of the breech, left stock flat, and top of the stock ahead of the buttplate tang as well as a circled script "MM" inspection cartouche stamped on the left stock flat. Numbers "24", "56" and "52" are stamped on top of the stock comb.

Fine, retains 80% original plum blue finish on the barrel with a few light scratches, 30% original case colors remain on the lock and hammer with smooth gray patina on the balance of the mostly silvered out casehardened surfaces with scattered patches of light pitting. Stock is very fine, with defined edges, numerous scattered dents and scratches, and an exceptionally crisp cartouche. Mechanically excellent. This scarce Civil War era Palmer carbine, a significant piece in the development of military arms as well as firearms in general, would make a fine addition to any U.S. Martial collection!
