As others have posted, it's not that old, what with a Nuvistor and all as part of the tube complement.It's likely to be a power amp that drove an industrial device such as a shaker table or a similar machine to produce vibrations. That would make sense with the Dr. Scholl's connection - they may have used it to test the vibration damping of their products. There is likely an on board oscillator that develops the signal that's then amplified.
It is likely bandwidth limited, but it had to be pretty well made since repeatability was important. There is some adjustment to the frequency range but it is likely limited too. The amplitude seems to be what it adjusted with the control on the face.
The chassis is in excellent shape, you could get a new faceplate made by Front Panel Express or ??, and rebuild the guts to hi-fi standards. That would save a lot of hassle and expense on a chassis.
It looks like a fine starting point for a nice project!
