Please excuse if this is not the proper place to post this question. I am trying to identify a sword my father brought back as a trophy from the Pacific after WW II. I also want to find out how to get it refurbished. I absolutely no idea where to start. The sword is located in the US, but I live in Norway. I want to get it refurbished before importing it to Norway as it is subject to an import permit.
Please see attached photo. I am not 100% sure this is Japanese, but since my father was involved in transporting Japanese POWs from the Philippines after the war, I cannot think of what else it might be.
