Bruce, thank you for your reply!
As for the tang, I understand what you mean but I personally don't know the best way to go about removing the orange rust, any suggestions would be much appreciated. As for the green and red on the scabbard, that is also a mystery to me, seems its the dye of the leather and is not painted, although the red piece at the bottom is a very funny and odd fit! As far as I am aware I am the only person to handle the sword since it was brought back from the war, even my grandmother never recalls my grandad touching it, not after he put it behind there wardrobe in the late 40's-early 50's!
