If the reflector turns out okay I think it's not in bad shape. One worry is
I've got a box of little glass pieces. No idea what they're for. They have
clearly been cut to size but other then that I've no idea. Plus a box of
metal cut outs. I haven't looked to carefully at them but that's a bit more
of a puzzle-)

Are the glass pieces large enough to be from negative holders? Same for the metal pieces. Could they be masks? AFAIK, these are not original parts of the enlarger.
Do you have the tapered ground glass for the lamp house, its the only non standard part there. The layers in the lamphouse are either standard ground glass (up to four or five layers) and sometimes a sheet of heat absorbing glass. Try cleaning a spot on the mirror with some alcohol or strong carbonate to see if its coated with lacquer. If it is you can probably salvage the mirror by cleaning off the rest of the lacquer and recoating it.
