I was wondering if anyone could give me some information on this large bayonet/sword? It was given to me by my grandfather when I was about 12-13 and I just dug it out of a closet at my parents' house. Nobody in the family knows anything about it, where he got it, etc., and grandpa is no longer with us. So if you know anything about it please let me know or if you can direct me somewhere to find information on it. Thanks The blurry pic is a square turned 45 degrees.
