This should help; http://www.tiger-tank.com/secure/journal.htm
While this is not a mid-production model, it is a early one, it should be of help.
Elfenbein (ivory) was painted on the upper parts of the interiors and gray-green on the lower interior hull below the hull sponsons on early models such as this one. Numerous small fittings such as vison blocks, crank wheels, gun sights, knobs, seats, etc., were black. Late versions had all gray-green interiors, such as found on the late model Tiger I at Saumur Tank Museum, which has this gray-green interior.....So, this isn't much help, since you want a mid-pro version. Things get weird here, you can have parts left in red primer, parts left-over from previous production models, parts cannibalized from wrecks, and to make matters worse, I don't seem to have a color photo in any of my books of a mid-pro interior. Maybe someone has a website handy they can give you.
