Looking to duplicate this;

Looks like a variation of the shadow compensating scheme Air Diagram 1164, Camouflage for Twin Engine Monoplanes - General Reconnaissance (Flying Boats). Extra Dark Sea Grey, Dark Slate Grey, Dark Sea Grey, Light Slate Grey.

Vallejo don't do RAF/Fleet Air Arm. I can find Model Air 71048 as matching Extra Dark Sea Grey, they call it Dark Sea Grey. It should be the same as Model Color 867 rack no 164 Dark Blue Grey. I have also seen it listed as a match for Ocean Grey. I have also seen Model Air 71053 Dark Sea Green and Model Color 994 rack no 166 Dark Grey as matching Extra Dark Sea Grey. Model Air 71013 Gun Ship Green is listed as a match for Dark Slate Grey. It is cross-ref to Model Color 892 rack no 87 Yellow Olive ??? I cannot find anything listed as matching Light Slate Grey.

Yeah I didn't think Valejo did many RAF colors. Any callouts for Testors, Model Masters, or Tamiya?

Thanks Antoni.
