I am trying to find a value for a Model 1856 Enfield Saber Bayonet. It's not for sale, just need some sort of value to put on it for the Friends of Fort DeRussy inventory list. The bayonet grip has been replaced with wooden handmade grips, the locking button is frozen, but otherwise it's in good shape. Anybody have any idea what something like this would be valued at on the open market?
