Correct. In early WWII when the need to identify and train large numbers of aircrew became apparent, a number of training devices emerged. One was the Link Trainer that had a little compartment that rolled, pitched, yawed and azimuthed (?) to the enclosed pilot's commands.
My father once wanted to build one using plans from a late 1940's Popular Science magazine.
("Hey kids! Want to have fun and learn a new career? ...) The idea was two frames connected by an automobile transmission universal fitting of some sort and controlled by a joystick and pedals. It never got built, and I think some of the parts are still in his garage.
During wartime any industry with precision machine tools was given contracts to the limit of their complexity. Turnbull Elevators would therefore have been able to make high tolerance but small production run parts.
@Jordan - this looks like a pamphlet or publication to capture those primary documents. Never mind if the story is thin, sometimes that is all you will get.
