If you can refurbish it I think it would be a good project. Take it apart and clean it well. Motors can be picked at yards sales, craig's list etc. Little elbow grease and some time and a little money should have you up and running. I have seen worse brought back to life.

Too old to use? *snort*
The older lapidary equipment is, usually the better built it is!
Motors are a dime a dozen. Okay 20 bucks oughta get ya one. Get used ones all over the place. Try craigslist if junk shopping isn't your thing.
May need to work on the water delivery system, but Home Depot has the parts you may need. Hard to check bearings by hand, but if you can spin the wheels freely it may be okay. Does the pan have any holes in it? If so, there are several ways to patch them, depending on how handy you are.
What are they asking? Under 100 bucks should be a deal.
There should be a belt cover (for safety) on the front of the machine. Easy enough to MacGyver one if need be.

Thats probably an easy fix. May need bearings so while it's apart put them in to save the trouble later. You will need a belt and some place to attach the motor. There may be holes on the back where previous motor was mounted. Rock out!!!!!

It looks to me like an old Crown Lapidary unit. I have a similar one with a rusted body sitting in my garage. If the frame is solid, bearings are good and the shaft is still true you have a good machine. Grinders of that age were more messy than today's. You were expected to get wet. They were built to last forever though.

I've picked up a couple new-old-stock [new, but has set stored for a while] motors for $60-65 at a local motor rebuild shop. That's about 1/2 the price of a new one. I think you would be best getting a 1/2 hp. motor.

I recently picked up a 4 wheel 8" Lortone Beaver. The recommendation was for a 1/3 hp motor, which I found for 1/2 price on new in really good condition

They are almost never too old, I think older is better in most cases.

There may be holes on the back where previous motor was mounted. Rock out!!!!! Welcome to the forums Dusty. Unless it not running smoothly or when you turn it by hand and see the shaft wobble you can probably run it for a while wo bearing change but if you plan on running a lot get some bearings nd the hubby can change I for you. Or if he's busy a small engine repair shop will probably do it if you have the bearings. . Belt working, ditto but if its looking a bit weak don't hurt to have a spare around but easily sourced at many hardware stores locally. The green stripes are really good and dependable.

1/3hp would work, 1/2 maybe better. The machine I learned on had two 10" SC wheels and split drums (I think 3 or 4) and an 8" Felt wheel. It ran fine with a 1/3HP motor. Look for continuous duty, resilient mount, 1725 rpm, open drip proof or enclosed. Make sure it does not say "air over" or AO on label. AO motors were AC blower motors and used the air from the blower to cool the motor so they overheat without major airflow. Speaking of overheating, avoid any motor that does not say "thermally protected" or words to that affect. Looks like a good candidate for refurb. Standard pillow block bearings if needed are readily available. If pan isn't badly rusted clean well and protect with good paint like "Hammertone" or similar.
