I'm a little dubious that the LM at Franklin institute is actually LM-14.
Has any regular gone and seen it? It seems to me that the LM is sufficiently
fragile that it wouldn't have managed to survive outdoors for very long.
I'm also a little dubious about the disposition of the un-numbered LMs cited
in "Chariots for Apollo", there seem to be a few too many, and again, I
don't understand how they could stand the weather outside.
