I like your comments on weight. I have some B&K 2203s (or perhaps some of them are 2209s) which I have been playing with. Together with a 1/1 or 1/3 OB filter set screwed to the bottom, they are a two-handed operation! I think you're right - with all this old acoustics gear, it's only really the mic and preamp which retain any value. But they're interesting, and evocative if you've worked with this stuff in the past.
