I've been fiddling around with this one of late- cobbling an interior together for it. This is some parts from an old Ordnance Models, (nee Tank Workshop) Panzer III/L interior with some scratched bits as well. Was trying to scratch it all as the TWS items are really very basic, but need more info and since most of this will be deep background once the lids are on I went ahead and took the easy way out. But I will scratch up a nice transmission one day...

Just need to dig for more exact measurements and drawings etc. Getting some initial coats of paint on, so as to get the interior buttoned up as soon as I can.
