OK, there are three documents which sort of fall into this class. First,
there is something titled "New C Compiler Features", no date, available here:
no date, but it appears to describe an early version of the so-called
'Typesetter C', mentioned in other documents, so this would be circa 1976 or
There is a second document, untitled, no date, which I have not been able to
locate online at all. I scanned my hard-copy, available here:

Sorry about the poor readability (it looked fine on the monitor of the
machine my scanner is attached to); fudging with contrast would probably make
it more readable. When I get the MIT V6 Unix tapes read (they have been sent
off to a specialist in reading old tapes, results soon, I hope) I might be
able to get more info (e.g. date/filename), and machine-readable source.
Finally, there is "Recent Changes to C", from November 15, 1978, available
which documents a few final bits.
There is of course also Dennis M. Ritchie, "The Development of the C
Language", available here:
which is a good, interesting history of C.

I found several documents which are bits and pieces of this.
Too busy to really clean them up at the moment.
