By some great stroke of luck a friend of mine saw this thread and sent me the link. I am the descendant and owner of Capt. William McCulloch's sword that appeared on the Roadshow a few weeks ago. I would be very grateful to see a copy of the book and will gladly pay for it.
Please email me at thecoolhandluke@hotmail.com, I'd love to talk further and share the info I've found so far. Many thanks,
L.A. McDonald
