Ed, The closest hunting sword I can see in Newmans Battle Weapons book is sword #87SS. It is a European hunting sword Circa 1750 - 1760. The length is 22-3/8", the blade is 16 3/4" x 1". It has pierced designs in a stylized shell guard with a curved blade. The hilt is brass. I see from the tag in your photo that that sword is 1650 vintage.
