Hi Jason. Last week I found a website that showed a variety of different models of vacuum operated wiper motors (from both military and civilian vehicles). There were definitely some models shown with a similar shape to yours. I am traveling at the moment and I cannot remember the exact website, as I was "surfing". I will try to find it later, but you may have luck searching through Google. The info is out there. Trico seems to have been one of the biggest manufacturers, I can't quite read the wording on your picture.
