Doesn’t look too bad! If everything is intact and the tilt is the only problem, It will probably clean up nicely. The back glass seems in decent shape. The great thing about restoring EMs is that you can take it as far as you’re able or want to go.
Basics: clean the play field and plastics, new bulbs, new rings, New ball, Triple-Thick the back glass, clean all the contacts to get it working again
Further: rebuild the pop bumpers, flippers and drop targets with new parts for a clean look.
Advanced: consider touching up and clearcoating the play field and re-painting and re-stenciling the cabinet.
Now is a pretty rare game, I think, and this one seems to have little wear under the grime. Good luck!
