Don't worry about parts availability, as those saws are thick on the ground and essentially valueless. I've been given a couple of parts saws just to haul them away.
As long as the pot metal gears aren't broken, it's an easy restoration. Bearings are a common part number and the gears and tilt mechanism interchange between different table sizes.
The locking bolt on the front is not enough to hold everything perfectly square. I always add a matching locking bolt on the rear trunnion.
When looking for the table extension wings, be aware Sears sold saws with three different table lengths. Naturally, only the correct one matches up. The the extensions were also made in cast iron (most desirable), cast aluminum and stamped steel (least desirable).
Some came with motors as small as 1/3hp. The Craftsman brand motors with cast iron end bells in 3/4hp would be the best for that saw. Just make sure you use the correct drive pulley, as they're available in both 1750 and 3450 RPM.
I use a notched V-belt, as the driven pulley is quite small and a notched belt bends easier.
