It is a universal. It is tilted straight up in those pictures, and probably would not normally be used in that position. You can see a graduated scale in the first photo. I'd imagine if you clamp the thing down, loosen those two large nuts on the 'shoulders' of the main casting, squirt a bit of WD40 in there to loosen rust, that you can rotate it back to the horizontal axis position.
To be really useful as a universal, you need the set of change gears and idler brackets that goes along with the unit when new. Said gears permit such feats as differential indexing, and spiral milling when a gear train is set up between the table feed screw and the back input shaft of the head.
First you get good, then you get fast. Then grouchiness sets in.
