I have one of his signed PDP-6 gift-shop cards and an email from Gordon Bell
saying these "To my knowledge, the museum has never engaged in gutting
machines for components"
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
machine.
