That is a Craftsman badged Atlas made 6" lathe. I have the same model - Craftsman # 101.07301.
It has bronze bushings for head stock bearings - easily replaceable, but will wear out, and best run at lower speeds than the Timken tapered roller bearing head stocks that came later. Because of this (and its fairly light build), the lathe really is designed around HSS tooling rather than carbide. Not that you can't use carbide, but you won't get the full benefit of using carbide at high speeds and heavy cuts. I've been using my lathe for a couple of years now. It's my first metal lathe, and i'm still firmly in the "novice" class. That said, i've done a lot of good work on this lathe. It's very capable if you work within its size limitations.
Yours looks well accessorized - with the quick change tool post, steady rest, chucks, and what looks like a micah undercutter and possibly a milling attachment??? Nice bench as well, with a reversing switch, good lighting, and most certainly more tooling in the drawers.
