^Odd that you wouldn't have thought of the NASM, considering that's where the miniature already is (albeit on the lower level of the gift shop) and has been for the past 39 years. It's already in the right museum; it just needs to be restored and put in a more prominent place within that museum.
No, I definitely know that. Had to ask directions there on how to find the hidden dear. Up the down escalator, so to speak.
