I purchased the home of a gentleman that once served in WWII. As we began to update and restore the attic we found a compartment (well made area tucked away in the floorboards) with two katana swords and one bayonet rifle. Based on the information that I have read I believe that perhaps these swords are from someone in Japan. I would like to know if they are real. I would also like to know the value if any. I currently reside in the Philadelphia area and I tried to find someone local to help me with this but I am having no such luck. Can you please advise me as to what steps I can take to find out some history regarding these katanas. Below are some pictures regarding my findings.
