Was out of an estate of a WW2 vet, and the son I purchased it from said "Dad brought it home". Thats all I got. No markings, no names. Looks very well made, and someone took some time on this. I guess I'm looking for the basics.. What country? What time frame?, etc..I Google-searched for about an hour and it made my head spin. Could find no definitive ID on it. I will say the fact that the butt of the handle doesnt flare out might be a clue, as most of these flare out. Who knows. It has very old patina/light rust that will come right off, but I hesitate to alter it before I know more about it. Would love to clean it up like new, but will wait on that. Handle appears to be horn. Any help here would be appreciated.
