Marty, my apologies, I should have known with your trips to Fiji that you would have been down this road, and reading that article reinforces my suspicision, and it is only that, but thinking like a bureaucrat ... try this one on for size:
The "bones file" is investigated and "closed" for all intents and purposes by the end of 1941. As far as a true bureaucrat is concerned, once something is marked closed, it might as well not exist anymore. WW II ramps up in earnest. While it doesn't disturb the vast bureaucratic machine that is the WPHC, it sure does give them al lot of other things to think about.
Meanwhile, a "new and improved" file numbering system is instigated by Vaskess, whom Tofinga once called "the Prince of bureaucrats." The bones file is part of the old system. It has already been marked P.A. (Put Away), which is a polite way of saying, "Not MY problem any more, buddy!" Vaskess is trying to keep up with the daily crush of running things during a war, when there is never enough of anything and every day brings the crisis du jour. In his mind, the bones file is over and done with, it has been marked P.A., it is Sir Harry's problem now, not his.
Which leaves the bones file where? Adrift ... without an "owner," so to speak. When it does surface again, say in a few years, maybe during a periodic consolidation or housecleaning, I can totally see it getting slapped with a new number under the new system and getting lost in the shuffle. NONE of which answers the question of where the bones are now, but I offer it as one plausible guess as to the resolution of the bones file. I will now return to shoveling snow. Oh the joy.
