Sam,
Your power supply is what may be a "socket power supply". An early, transition design to take AC and divide it to A/B voltages for earlier battery sets like the SW. Thus the wires hanging out to connect to the battery set you have.
Socket supplies were made to plug in to a lamp socket with an AC plug adaptor screwed in. Most early AC homes had only a few lamp sockets hanging from the ceiling and needed the screw-in adaptor. Wall outlets came later.
4-tube collecting for me is much like my tv set collecting. Grab the best looking and fix the rest. No need to get hit with flying veneer or mystery boxes added years later. Most 4-pin sets fit this and can be found very cheap.
Next, you get to learn about transformers!
