Thank you both.
Robert - I'm sending to your house on a very, very, very, slow slug. It should get there in 20 years.
Also I looked closely at the torn parts of the leather and they do not match, sadly.
By the way, would you post a picture of the frog attachment to which you refer?
Ian - the cross section of the blade is diamond shaped. It took a few hours or so of work for cleaning, shaping the silver replacements, and making the silver nails.
I may get with an expert leather worker here in town for the scabbard - to stitch and re-enforce some places in the leather, and to make the missing section.
