The sword is a variation of the Grosses Messer, in that the grip plates are not rivet-attached to the tang. Instead, the grip was secured by a pommel, pommel plate, or a metal handle-shaped end. The sword is 1-1/2- two-handed; the long grip provides sufficient counterweight for the blade. It dates from the first half of the 16th century, possibly originating in Germany. I don't see any marks that clearly point to the Stantler family. A beautiful, original piece.
