There is also the Usenet posting which you forwarded:

The 'garage sale' is documented in one of the Museum's reports
At first I thought this was the smoking gun, except it happened
in the fall of 1983 (the 6 was shown at DECUS in June, 1984).
They did disassemble more than one PDP-6 at that time according
to the article.
So, the short answer is they had PDP-6 modules, but not from Stanford's
