I haven't been up there for a coupla' months - maybe they'll put it back - so the kids can see that Thomas Jefferson wasn't allergic to guns. Or maybe they already have. I think it would be a good idea.
UPDATE 2/19/11 The "lighter" is a case for the mini-draftng set spread out. I think the "ruler" is a tiny engineers scale, and the "feeler gauges" are ivory sheets riveted together to slide, a mini-notebook you write on and erase with a pencil. Notes still on there.
