Patience and diligence finally paid off. I found my 10OT and for far less than fifty-sixty dollars. Less than twenty.
Now, you regulars know I go for oddities, and dead mint knives in the box are the exception for me rather than the rule, so this one is a bit used, though not abused or used up.
This knife has not the Schrade, Schrade-Walden, nor Ulster tangstamp. In fact, no tangstamp. My guess is that it was an SFO and the identifyer was a blade etch, either quite faint, or gone altogether. A Primble? A Higgins? Keen Kutter?
According to the article on Larry's site by Dennis Ellingsen (
http://www.collectors-of-schrades-r.us/articles/PrinceAlbert.pdf ), Ms. Chase, former historian at Schrade, dated 10OT production to the years 1964-1967. Please note here that it has been my experience that published production dates are usually taken from catalog appearances, and that it is likely the 10OT was actually produced a year earlier (circa 1962-1963), and much later as fulfillment of a large outstanding special private order (such as for the Prince Albert Tobacco promotion).
The knife is still in the postal system, but when it is here under bright lights and magnification I might find the ghost of an etch. Or an extremely light tangstamp.
