Not sure if this will help, or hinder Andy.
This is the A-8 at RAFM Cosford, when our forum member Rodd was working on the tail wheel retract cable (after I had told him of it's existence , ahem!).
This example was part of a "Mistel" combination captured in Denmark in 1945, and the internal paintwork is original. The wheel bays and gear legs, along with the STC carrier, are RLM 76, and most wartime pics show what is most likely this colour. (looks darker in these shots due to lighting conditions.)
I don't recall seeing any evidence of RLM 02 wheel bays, in general, on either FW190s or Bf109s (after the E model), or any post late 1940/early 1941 Luftwaffe types, although there could be, of course, exceptions (deliberately planned by the RLM to f*ck up modellers long after the fall of the Reich !).
