I found it!!! This is kind of "what have you left on the table." I had this anvil on watch list with eBay, thinking
it was kinda like what was wanted. It sold on Nov 17. I went back over the list this morning, having spent
a lot more time looking at the Civil War measured drawings, and realized this was the one we'd been looking
for, but left it on the table...
On the plus side, I've located a fellow in Virginia who will make one from the plans -- and now the photos.
Unless somebody here knows where one of these is lying under a table in a junk shop somewhere...
