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 were delivered too late to see action. It has small inspection initials on the left of the breech and left stock flat, and a circled script "MM" inspection cartouche stamped on the left stock flat.

Excellent plus, as issued, retains 98% original plum blue finish on the barrel correctly with wavy lines in the finish as factory applied, 97% plus vibrant original case colors on the lock and hammer, bolt handle, trigger guard and buttplate. Stock is also excellent with attractive original raised grain, a few minor handling marks, distinct edges and crisp stampings. Mechanically excellent. This excellent example of a scarce Civil War era Palmer carbine would make a fine addition to any U.S. martial collection!
