I have seen a more "up -to-date" version of this a couple of years ago...

it is a "variable inductor". By hooking the approprieate AC wire to the "L" 
terminal ( 1,2,3) and tapping off of the other (1-8) lugs, you change the 
inductance of the unit.

You will find that all terminals are connected with minimal change in 
resistance between each point ( for a working model) check carefully for 
shorts, the insulation on an item that old may have failed. If you test 
with a variac, keep the voltage low ( 20-50V) and use a 5- 10A fuse to 
protect until you are sure the are insulation is viable.
