After a few flights in the Tu-154b model, I was somewhat disappointing to get back into the Concorde (which, modelling left aside, is the plane I like better), since there is a vast difference in cockpit texture quality. Here's the standard Concorde cockpit as it comes out of the box:
Looks a bit flat and not very realistic, especially when you look out and see Custom France Scenery or something like that. So I decided I wanted to see something nicer when flying Concorde and looked around how the cockpit actually looks
Here's the real thing
Based on this and a few other pictures, I modified the cockpit by changing the color-scheme and placing more detailed, metal-like textures on some of the panels. All buttons got a 3-d effect, and the gauges got a background socket to agree better with the look of the real cockpit. Also, I gently changed some positioning details of gauges.
Here's the result as it is now:
There are still a few odds and ends, and I haven't tested all functionality yet (for example, when changing the size and internal shift of gauges, they may not work correctly afterwards) and the night lighting looks a bit unusual (I don't know if there is an easy fix though). And of course I am of a mind to add more texture details to the inner hull - so this rather is work in progress.
Since it's not my model, I have no clue if and how this cockpit design could eventually be distributed. For the time being, if you are interested in testing it, please drop me a PN and I'll make it available, provided I get a bug reports and further comments.
(Edit: I have since made the package available here - explanations an instructions further down).
