My Laborator 1000 (ancestor of the Durst L1200) can have the head tilted.
This moves the negative stage AND the lens stage. There is a contraption availlable into which one can mount the lens and tilt it regarding the lens panel;
This way you can move 2 planes out of three. If you need to move the easel, you've to have a set of shims on hand...
There are no scales on the tilt. Be it head, lens or easel ;-)
