This was Manfred Dieterle's plane. As mentioned above, its a nightfighter. It was used in 'wild boar' missions (wilde sau).
The planes didnt had radar onboard. Ground radar led them to the bombers. And if possible, they got support from flak search lights.

Yellow "1" of Staffelkapitan Lt. Manfred Dieterle with an interesting camouflage scheme for nightfighters. The underside and wing root are black with no Balkenkreuz. The upper surfaces are RLM 76 with wavy lines of RLM 75. The spinner is black with a white spiral and the RV band is rust-red.
I like it very much and hope to see it in the game.
