That mil/drill is looks like an RF-45 clone. I've got one with the dovetail column and paid WAY MORE than $250 for it! Good score. Excellent rebuild article on a RF - 45 here:

If I can make a suggestion on boring bars, for the mill those sets of brazed Carbide are good value but do need a bit of a touch-up from new, I'd invest in a 3/4" boring head as well. For the lathe I like LH boring bars as it allows better optics and with a 3/4" bar can be used in the 3/4" boring head in the horizontal position which reminds me that I need a LH 1/2" bar!
I agree with
WalterC about Mesa Tools, well made good quality at a very keen price.
