These masks were drawn from the Tamiya instructions for their Mk IX Spitfire but are probably useable on many types as a generic scheme. Please note, I drew these for my own use, they are not perfect and not professionally produced so will probably need "tweaking" if you decide to use them. The screenshots show location of the camouflage sections, it presumes that a base coat of Ocean Grey has been applied so these allow for Dark Green only.
UPDATE 26/3/21 I've amended the file for the fuselage; on fitting the masks to my model I found that I had omitted to provide a mask for the port side above the tailplane, this is now included and positioned on the sheet in the bottom right hand corner. Also amended are the engine panels, the original versions were too high.
UPDATE 27/3/21 Another amendment, the fin flashes were slightly too large but have been altered to fit. I've also added the mask for the upper engine panel, shown on the sheet as "Nose".
