Most of the important horizontal parts except for an overarm support and an arbor seem to be there, judging by the second pic you posted. The table looks like it will go down further, and the mill vise swivel base could be removed (semi permanently if it was mine) to get more headroom under the spindle. It would be good to know which Bridgeport head is on it, some of them are fairly rare, and some have very expensive and a bit difficult to find collets to fit them. If it comes with a good selection of collets, they you should be OK. Speaking of which, what else comes with the mill besides what we can see in the pics? Also, I second the thought that you will miss not having a quill for drilling and boring holes...
