I have just finished the ICM Merlin, for my Mk IX (don't tell me its a poor example - seen that in other posts) - I can live with it). Now I have looked at a tone of pics and I read somewhere that Edgar mentioned something about grey ext, However I have the 1/32 book by Brett Green and Co on the Tamiya Spitfire and there the Engine seem to be solid black except for exhausts and top covers. I have been told that in service, an engine is just a big black block. Its primed and ready for a dash of colour or not. Thoughts please.
