I agree, and thanks for the clarification Darryl.
I had heard about black seats, and have seen some photos of early Spits where it appears the seat might have been black, although of course, being B&W pics, it's difficult to be certain, especially taking into account the lighting, print reproduction etc.
The question is, was the black the actual finish colour, or a primer-undercoat, perhaps sometimes just left without painting the green, due to production demand etc ?
When I did the AV presentation production at the BBMF back in the early 1980's, I seem to recall that one of the Spits appeared to have a black seat (I'm fairly sure it was the MkII, but may have been the MkV), but I didn't take much notice at the time, being awed by the very act of sitting in the cockpit, and just assumed that it had been re-painted at some point in its life.
