Thank you everyone for your input. I can say with certainty the sword came out of a footlocker, but the family had very little information about their relative who served. I was able to see most of the stuff in there and picked this sword up pretty cheap. I got another sword and a type 14 Nambu as well. All they said is that he served in the Pacific, but who knows. They stated that there were other swords that they had sold already. I was not the first person to get access. Its very hard to tell, but the hamon looks real, but very hard to photograph. Its only visible in certain light. Does not look like other fake acid etched sword hamons that I have seen.
Bruce, I tend to post over at WAF and WRF. I am the Paul G who found the ebay auction with the "NLF /souvenir sword" and PX sales paperwork.
Matt, I dont see any extra holes inside the Tsuka
In any case, it looks like its been modified a bit, for any number of reasons. Where, who knows, Why ?? , possibly by the Vet, but am very confident it was not by the family. At worst, they may have shined up the blade a bit, but not sure. I just always had that feeling. I am going to move this along, and will give this link to the new owner. I got it cheap, so I will move it along for what it is.
Thank you everyone,
