It's a Craftsman (King Seeley) 103.23130 or possibly a 103.23131. The speed reducer is baller, and it's needed as you have a 1hp motor on this. They usually came with 1/2hp and occasionally a 3/4 HP motor. The wiring is to offer forward/reverse most likely. It's worth keeping if you can box it off so it's a little safer. I'm restoring a similar benchtop and floor model right now, and am happy to help with any Qs you may have. Before you get too far into it, I'd suggest you pick up an alignment gauge to check your spindle runout. If it's bad, it's probably not worth redoing. Out of the gate, I'll tell you the only real hard part is replacing the bearings. You'll need about 4-5 gallons of evaporust, 3 cans of spray paint - Rust-Oleum/krylon fusion smoke gray is about as close as you'll get, and depending how crazy you want to get, about 8 hours on a buffing wheel. If you're going to do the column to a mirror finish, it will take a bit longer.
The post on garage journals is great. I'd HIGHLY recommend watching the YT vids from "small town machine shop" to disassemble. The way the seperated the quill, upper pulley, and top two bearings is MUCH easier than the way it is outlined in GJ.
Your missing the table lock. I may have one if you need it.
Here's the manual if you don't have it yet.
