My first lathe was one of those. Sears made by Atlas. Be careful of the Zamak half nuts. I had to change mine every 6 months as they wore out. No longer available except used on Ebay from old lathes being parted out.
It took all day to make parts that I could make on my next lathe,a Jet 10x24. I could not take much of a cut with the Sears as the bed is way too thin. And,you don't want to put much strain on all those Zamak parts.
I THINK Sears was painting their machines gold back in the 50's. So,no telling what condition the half nuts are in. Close the half nuts and rack the carriage sideways. If it moves MUCH,the half nuts are worn out. Check the teeth of all the gears,too. the ones behind the headstock are all Zamak. The cover seems to be missing.
I'd pass on buying it. But,if you only want a lathe for occasional use in the home shop,and are not planning to be using it very actively to make models,it may be o.k.. Certainly there are a lot of Atlas lathes out there. But,years ago,before imposts.Atlas made the only affordable lathes for individuals.
