Volker:
Thank you for posting that photograph. It is a LVG.B.I. The uniform darking coloring indicates it was acquired prior to the war, confirmed by the original national markings. The machine was painted grey as were all military vehicles prior the war. The national markings are 1 meter wide, instead of the 500 mm band used on most aircraft.
Blue skies,
Dan-san
