Interesting. I have one of those too. I got mine for $50, cleaned it up and built a new bench top for it and now I use it frequently in my big shop back home. It’s the original model, the 10ER and was built until the Mark V came out in 1953. It should work just fine.
I have a blog on building the sander that I can re-post here if you are interested.
