That's an interesting picture of the XP-75 cockpit. It appears to have been "tweaked" at some point. Note the row of toggle switches just to the right of the artificial horizon caging knob. They're floating in air with the end switch shown as if it was mounted across two different surfaces at obviously differing levels.
I see that the same photo appears on the USAF National Museum website, on the uscockpits.com website and over and over again elsewhere on the net.
Btw, I'm not disputing Planegill's identification of the cockpit. David just doesn't get 'em wrong. I simply find the modification interesting and I wonder where and when it was photoshopped.
Cheers,
Glenn
