Above the ‘observer seat’ or ‘jump seat’ is also a commercial (Grimes light) for the direct lighting.

The ad I have a friend cockpitbouwer. This ad is made for 24V DC and one can see it with the red dial for dimming.

The outside of the ad had his good time had. The markings were not clearly visible and there was left and right of the lacquer is gone.

I have the ad so a little bit renovated by the paint, and the markings again.
