Bendix 200 Series Computer Controlled Automatic Test Equipment: Theory and Operation Training Manual Model 260. Aug 1, 1969.  Prepared by James Raffetto.  Hand signed and numbered.  8.5" x 11" spiral bound softcover.  Well over an inch thick.  I suspect that there are a few pages missing from the alphabetical glossary of terms at the back.  It stops at "Turn-Off Time" and there is no back cover.  From a non-smoking home.
