Tnanks, Zathros. Nice pics. There is a lot of shuttle photos around, but every time I find something previouslu unseen... like some of the images you posted. It's all good reference material. Every photo is taken by a different angle so there is something to learn from anyone of them.
Unfortunately I wasn't able to find any official NASA reference about the mission specific panels mounted on STS 134.
BTW, in my previous post I talked only about panel numbers without explaining where the panel really are. Excuse me, my mistake.
Here is the location of the panels for which I don't have complete references (yellow areas).
Anyway I completed left aft section. It was pretty difficult as, lacking schemes, I used only partial photo references to reproduce all the details.
All I was able to see in the photos is here. All the rest isn't. I preferred not to place any particular for what I don't have an actual image or drawing.
At the end of the work this is the complete rear-left consolle.

The lower section was completely redrawn on a totally cleaned surface.
But the piece of equipment I'm more proud of is the Multiplexer with the audio-video connections panel.

Even if no scheme was found of this equipment, I had a very good photo where almost all the labels were clearly visible.
The result is pretty realistic. I like it very much.
A different story is the L12: the "standard switch" panel

At every mission some templates was placed on the panels covering some of the little windows (not in use) and providing personalized labels for the switches with the functions they actually had in that particular configuration. I see only a little part of those templates in my photos so I should have added all the remaining detail based only on my fantasy. I preferred to leave the panels in their "base" configuration with no labels (except the numbering of switches and displays) instead of inventing.
Here is the lower section with some little doors and a handle I desumed from the great Gigapan Endeavour panorama (my main reference during most of my work).

This is all for now. Next time I'll draw the right aft consolle.
Bye!
