I've got a Philips PCS130.
- Both. See attached diagram from the manual.
- Both the head and the lens stage rotate freely, although they both "click" into place in the conventional non-tilted position. Knobs tighten them into position at any angle so the rig doesn't get accidentally knocked out of alignment.
I've never actually used this feature of my enlarger, so I don't know how well it works in practice.
