Saw this article and discussions afterwards, figured I'd contribute in a small way.
I'm currently located in Virginia, and have been fortunate enough to get to know the folks that manage the Aberdeen collection at Fort Lee. Once the Elephant is returned to Fort Lee, I could potentially get some photos of the inside. I know it's in poor shape given the lack of funding, but there is discussion regarding the refurbishment of some of the collection. More to follow as events unfold but once it's returned, I'll be sure to send photos.
