I took several pictures of an original early 29 with no upholstery. If you email me I can see if I still have them in a couple emails that I can forward to you. tjw2831@hotmail.com
I used "Restoring The Open A" a lot building my Pheaton. There is a picture close to the back of the book, of a body with all the body wood installed. Was very helpful with the "jigsaw puzzle" wood kit. Phil.
