This is an original three-band stock for a Springfield Model 1863 .58 caliber rifled musket, Type-1. Stock includes the metal ferrule or cap at the fore end of the stock, as well as the rod retention "spoon" spring. Cartouches are faint but visible on the left side of the stock where the lock is housed. There is a small gouge on the left side of the buttstock and some checking in the end where the butt plate would go. A few minor dings and scratches, but overall this piece is in amazing condition for its age. I tried to get closeup photos of any areas of concern.
Online research shows that these were produced during the U.S. Civil War years of 1863-1865. Further discussion with some collectors suggests that many 1863 Type 1 stocks were later cut shorter to make 1868s, making this particular configuration much less common. This stock can add value to any serious collection or be used as an original and period-accurate replacement to improve an individual piece. I found a company online selling modern reproductions that still need inletting work for over seven hundred; this one will start at well below that.
