Rensis Likert was the Director of the Institute for Social Research at the University of Michigan. It is still a thriving operation and I would suggest that you write or preferably call the office of the director there and inquire how you can obtain a copy of this instrument. His book, New Patterns of Management is one of the original writings developing his approach to management which he called system 4. If you have difficulty after trying this, e-mail me at cseashore@fielding.edu. Good luck, Charlie Seashore
