Pic 1 is my side wall. I can confirm thats Art Deco.
Pic 2 and we are in place with lots of nut plates and other things I didn't document. Like how the various cover pieces fit into each other to minimise the fasteners required. Isn't this log long enough already? Lets just assume quite a few hours went into getting to pic 2.
Pic 3 is while I'm thinking about foot rests and a cover for the trap door in the left corner. I might get some rest for a minute or two.....
