That's the lighter duty series Sheldon made. They are perfectly adequate for a home shop. Every bit as good as a South Bend. Looks reasonably well tooled. I see a genuine Aloris toolpost (not sure on the holders), a Jacobs Superchuck, and a good selection of lathe chucks and rests. What are they asking? In my neck of the woods, that would probably bring $2500 in a private sale, maybe a grand or $1200 in an auction.
Sheldon also made an industrial line of lathes called the "R" series. I had one, they are excellent lathes if you can find one. Every bit as good as Clausing Colchester or LeBlond Regal lathes.
