Hi, I was given this Japanese sword by an old family friend who was an Army Officer in Burma towards the end of WW2. This sword as told belonged to a Japanese Officer. We would like to know if possible please some information relating to the sword and have pictures showing the identifiers on the sword along with the original tassel that was attached. Any information as to how we can clean up the sword for display purposes would be much appreciated and anyone who knows more of the history would love to hear that too. Thank you
