Hello,
I am preparing to sell a Dungeon Masters Adventure Log on ebay and could not match the one I have to any of the variations on the site so I thought I would post a note here.  I did find an old thread that references a copy that is like mine and implying that it might be a 4th printing.  The details:  Old advanced D&D on top, cover red. Three hole punched with armor and weapon sheets at front and back.  Pages unnumbered throughout. Inside cover printed in black ink.

This may verify a previous spotting of this variation or may represent what 4th printing really is since previous 4ths did not have armor and weapon sheets which were presumed to be in the middle of the book.
