Interesting drill. That looks to be an Atlas Craftsman drill press from the early 1940's. They are really nice quality. I cannot tell from the photo if it has the chrome spindle cover on top of the spindle pulley cover. They are often missing and a bit hard to find.
I slightly disagree, I think that DP is mid 1930's. There is no on/off switch on the side and it has only 2 handles on the feed. After 1936(?) they had 3 handles, and shortly after went to 4 handles.
The $125 pricetag is OK, but I'd have trouble pulling the trigger. That's only because I'm a cheap *******. It should be worth that price if it runs right.
As for the spindle cover, you're correct, they are EXTREMELY hard to find. I spent a year and a half
actively searching for one to complete my grandfather's 1942 model. I finally found one this month for $57 w/shipping (which kills the cheap ******* theory on the back end). They can go for more if you can find one.
The info on the reduction pulley seems correct. Mine is the taller version that came with the DP when it was new.
I have what looks like the same Dunlap motor on mine, it was bought by the original owner when he bought the DP new. It's still going strong. I'm the third owner.
All in all, that's a great drill press for an active home shop at a decent price. It will need some fine tuning, but nothing too difficult. The paint looks to be in great shape, and it still has the SKF bearing sticker on the front.
