" Do nothing machine" skills testing machine

[Rodneyjax]

I have been searching for information on a machanical aptitude testing machine and found old threads (635-37859) refering to the same. I have one. I was looking for anyone with info or manuals for this. The story that I got was that Proctor and Gamble made this machine to test possible mechanic trainees. It has a small block that represents a bar of soap and it cycles through a series of movements. If anyone can add to the story, please do. Would like to know the value of this heavy little machine. Everyone loves to play with it and a few guys that I work with remember them from way back in the day. Thanks
