Too bad I don't have a date but I found this single page of the support system for my second generation projector design.
The first design didn't have the 23.5 degree tilt as I really didn't understand at the time. This allowed the original design to fit in the large center section with a 23.5 tilt. I was going to use "O" gage train track around the center section as power slip rings. I was young building more of a artistic model of a projector then a working one. Thankfully this never made it into production and getting the book "From The Aratus Globe To The Zeiss Planetarium" enlightened me as to how these projectors actually worked. From there came my third generation idea which made it out west with me.
