Thankyou, Grey and Joe...I am very happy, that with your assistance... The sword now has a makers name to go with it....I will pass this sword on to my son because of the military significance it has with our family....
The very high humidity in New Guinea and the Islands would have caused the early corrosion under the handle, and knowing what I know now, I still would have been tempted to treat the damage on the nakago....I'm glad the blade is still in excellent condition....
For storage for the next 60 years of more, is just a light machine oil good enough??....max...
