Chuck, you should receive a Nobel Prize for your work! I've been modeling on and off for years, this work is absolutely amazing. I would challenge most humans to tell me that was a model. Your work has inspired me! Thank you!!
You should seroiusly consider writting a book Chuck. Your work is truely remarkable and there would be a line around the block if you compiled this all into a how to book. I know I'd be in line.
As a retired electrician I believe that period wiring might have been knob and tube. I was sometimes run on the surface of the walls. Also inside as you have nicely done in the office.
