Hello. I am completely uneducated when it comes to identifying swords.   My father-in-law owns this sword and told me that his USMC father brought it back to the states when he returned after World War II. neither of us know the history and this is why I seek your assistance. Please examine the pictures and let me know if you could shed some light on this.   If possible, I would like a translation of the Signature, history of the maker and history of the sword if possible. This is very fasci
