But you has to know that these colours of the wheel bay and also the leanding legs could vary from kite to kite. The base is the RLM 02. However it seems that these could be of the RLM65 , especially the "trough". What is more there was a leather or fabric "pinny" inside of the main hole. While the canvas one could be painted for protection against water, dust , mud etc..( but no evidence ) the leathern one preferably not. So it could have been of the brownish or tan leather tone.
