The Seymour and Criss pairing is pretty amazing.
I have to say that I find this MUCH more persuasive than theories of sheets. It is almost like the scratched plate is the T206 Rosetta Stone!
I will forever now be obsessed with finding P150s with scratched on them. If only I had paid more attention when I built my Momster a few years ago. The SGC 10 Magie above was once mine, and I never even bothered to look at the back much. Was too focused on the "i"
Great work! Please keep it up!
