Just bought this katana? Supposedly, the dealer I bought it from said that he found it wrapped up in a WWII USMC utility blouse from a family, so it is thought to be a bring back. However, I am totally knew to Japanese swords and do not know what I really have. Scabbard is wooden and metal guard is loose, so assuming it wasn't made with high quality materials. No markings apart from what's on the scabbard. What is more interesting are the animal symbols which look like deer along the grip and on the pommel. I have not seen this on any other examples and am going to look closer to see if this is gold or not. The question I have is first, is this a legit Japanese sword and is it WWII production or even a family heirloom? Thanks.
