That is a following rest for an Atlas/ Craftsman lathe, looks just like the one I found yesterday, except mine is in need of a lot of TLC. I also found a milling attachment too. It’s complete except for the removable jaws, and it is in similar shape; rusted and frozen. As often is the case, the PO had passed years ago and there was no one to take care of the old man’s tools. Some estate sales are better but you pay a premium price; I’m more of frugal guy that enjoys restoration work, taking on the rust.
