I agree completely about the need for solid documentation to really confirm this knife as a unique artifact of the '60s, not "just" a unique RMK. But that documentation would seem to be relatively easy to obtain compared to many personal items of the period.

If I had planned to commit serious cash, I would have initiated or commissioned that documentation effort, before bidding (perhaps someone did). That would have included official records, and contact with family members listed in the obit.

The original offer on E-bay did not include the officer's name and history. But based on the marked sheath, an internet search brought his (possible/probable) identity to light several weeks before the close... plenty of time for an in-depth look at the records.

Your thoughts on what documentation is needed is spot on, IMHO.
