The Palmer carbine holds the distinction of being the first metallic cartridge bolt action firearm ever adopted by the U.S. Army and among the first bolt action firearms accepted by any military. Adding to the Palmer's value is the fact that only 1,001 of these carbines are estimated to have been manufactured, all in 1865 on contract for the Union Army. They were delivered too late to see action in the Civil War. It features a blade front sight, notch and folding leaf rear sight with 300 yard peep, "U.S./E.G. LAMSON & CO./WINDSOR VT" and "1865" on the lock, multiple "MM" inspector markings including a cartouche on the left stock flat, and a saddle ring and bar above the trigger on the left.

Excellent with 95% plus of the original blue finish along the barrel which has taken on a plumb brown appearance, 97% plus vibrant original case colors, some slight spotting and minor marks, some dings (mostly on the wrist) on the otherwise very fine, and some slight surface flakes. Mechanically excellent.
