28" s.e. blade. Weak HORSTMANN PHILA name to the ricasso. Keystone mark opposite indicating the blade's manufacturer as Emerson & Silver of Trenton, NJ, referred to as the "Keystone Works." Horstmann would buy blades wholesale from various manufacturers and mount them on hilts for resale, but by the Civil War had mostly come to rely on German suppliers thus indicating this as pre-war production with its American blade. The blade quite bright. Hilt excellent. Original leather scabbard with fire gilt throat mount, lacks the tip mount. Very exceptional example from the famed American Sword Collection of Frank Barnyak.
