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 to late too see action in the Civil War but would have undoubtedly been very popular compared to many of the other single shot carbine designs used during the 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, "366" two the left of the chamber, multiple "MM" inspector markings including a cartouche on the left stock flat, a saddle ring and bar above the trigger on the left, and "P" marked buttplate.

Excellent, as-issued. 98% of the original brown finish remains on the barrel. 98% plus of the original vibrant case colors remain on the lock and hammer, and the other casehardened parts retain strong original finish and have more subtle colors. Even the screws retain most of the original niter blue and straw colors. There are a few light marks and a few faint pits. The stock is very fine as expertly repaired and refinished and has very faint evidence of a prior crack in the wrist extending back from the tail of the lock, distinct cartouche and other markings, and some minor dings and scratches from storage. Mechanically excellent.
