Boy oh boy, they didn't leave much did they.
I hate to say it, but I dont think it's worth restoring back to original, unless you happen to find a complete machine that's had the legs cut off or has been attacked by borers or something.
Just to get the cabinet right, you'll need the motor board, tonearm board & the timber surrounding the motor board, as well as a door, the hinged grille, the stretcher between the horn & record compartments, the two pieces of timber beside the grille, and the shelves.
It should look like the picture below.

Then you've still got to get all the right running gear.
The original tonearms for these are made of pot metal, and due to the poor design used to hold the tonearm together, they are extremely easily broken, so when a good tonearm comes on the market, they will often bring huge amounts of money because so many people are looking for a replacement.
Then you'll need the complete horn assembly & graduola device.
These also incorporated a unique automatic braking system where you'd swing the reproducer over to the end of the record & push a button at the front left of the turntable, to mark the position where the brake would be activated after you played the record. I sold two pieces of this braking system on ebay about about 3 years ago & got around $50 for the pair, so they wont come cheap either.
Then you've still got to get a soundbox, motor, crank, needle cups, lid stay & possibly even the crank escutcheon. The picture below is what the interior should look like
It could take years to find all this separately here in Australia, or you might get most of it all at once from USA, but with the cost of freighting a large heavy double spring cast iron framed motor as well as everything else, it could end up costing as much as 2 complete machines here.

If it were mine, I'd probably fit it with sturdy shelves & use it for additional record storage.
Another option would be to make it into a frankenphone using the parts you already have. A fairly decent sounding horn can be easily made from plywood, but there'd be a lot of cabinet work involved, and you'd probably have to drill a new hole for the crank & plug the original hole, then refinish the entire cabinet.
Even though the machine would have no collector value, at least you'd have a machine to play & enjoy that was a lot better than the cheap reproductions from India & china that sound like crap & ruin your records.
