It's a DC power supply for the old two rail guys. That finned thing is a selenium or copper oxide rectifier. I bet the polarity of the output voltage changes from the switch being at one end and with the switch at the other end.

Thanks! You’re correct abut the polarity reversal. As you pass through the center position, where you see the lever in the photo, the polarity reverses. I have no intention of using it, I just thought it was pretty neat.
