I said I thought Jim's arguments were good. I'm not sure they are convincing. And I don't really know what any of the braces were for. Here is one window brace inside 1009;
The particular assembly and application of these straps seem to suggest that they were meant to make the framework of the windows more rigid.
I find this primus seems more logical to explain the outside diagonal irons as well - or at least the attempt to reduce the side to side motion and what it might do to the operation of the end windows. As hand grabs the diagonal braces seem awkward . Not saying the cupola windows were not used to exit the car onto the roof but those irons are just not convenient for that. If you think about crawling out of the window (belly down) why do you need to grab an iron splayed off at an angle? You may make better use of the edge of a walk board. If you hoist yourself out then a grab on top of the roof would be more convenient.
As the car rolls down the rails they swayed and bobbed and twisted. Enough of this and maybe the windows don't work so good. Perhaps the irons were meant to increase the rigidity of the cupola to help reduce the operation of the windows on the ends. Maybe the braces were angled to increase their horizontal reach - their effectiveness as structural members. And maybe they were not as necessary at the short roof end as the cupola sat on top of the end wall of the body and they simply didn't make any difference.
After a lifetime of structural awareness from playing with tinker toys and building blocks as a little kid to drafted for structural engineers and designing custom homes - maybe one develops a sense of what makes physical sense? Just my thoughts for what they are worth.
