Here's a site that has some interesting blueprints, as well as free downloads--including some free programs to look at the blueprints and other files.
This site came recommended to me from a Louisiana "lawer" friend of mine who is also a big Civil War and World War II buff. He too has a 1:16 scale FOV KT!
Here's the link:
