On another note, has anyone ever seen patent documents for the Norelco Protelgram unit? I assume it was patented somewhere, although a quick search of US patents didn't turn up anything.

I think probably patented in the Netherlands by Philips. I have one protelgram projection unit made by Mullard, much more robust and heavy duty. The optics are claimed to be f 0.62. Now THAT's FAST !!!
