Thank you Mr. Barker. I believe you may be correct about it being in private hands. I did a lot of google searching yesterday and found a blurb on an auction site that suggests it has been sold/acquired privately.
I was hoping for pictures of the backside of the sheath, better pics of the strap, and approximate strap length.
I know someone, if I can reach them, who should be able to figure out strap dimensions based on measurements of the tomahawk head that are given on one website.
