Thank you Geraint and John for the replies. And yes John I did some research, however I found a biblical flood of information and without studying swords as you folks do I'm out of my league. That's why I'm here.
Here's some additional pics. I hope they'll help determining the swords age.
Thank you again, Jon
P.S. Forgot to add, the measurement from the tip to the notch where the habaki starts is 24 3/8'.
