Brian,
Many thanks for your help. Unfortunately there is no date on the other side - is there anywhere else I should look?
As I understand it, Kanenao is the swordsmith's name and Noshu Seki ju refers to the place it was made. How should I read this last bit? is Noshu Seki the place?
Could you suggest any way of finding out more about the sword?
Many thanks once again,
Doug
