WIWOC ...
Can I suggest you drop Rod Brown an eMail, he and Bill Fisher, amassed over the years a wealth of information and pictures of the dear old Chipmunk.
I can only recall the Matt Black cockpits ... but do remember some we're "chipped" (pun intended) showing a green'ish colour underneath ... But this may have been a primer paint.
He's ex RAF and I'm sure he'd love to be of some assistance if he can
