The plans have been found. They'd gotten buried under tons of other stuff that had nothing to do with my research.
So it was off to the archive again. Took some pictures, put my brain to work. I'm transforming it into text as we speak. Still a long way to go, but we're getting there. I'm on page 13 or so and steadily progressing. I've also done some illustrations and worked out some visual comparisons which I'll shove in somewhere in the back.
I was also working on an interactive website, but I'll see if I still have time to finish that up.
Anyway, must get back to creative writing before my cup of coffee runs out and writer's block sets in again.
