I have not seen one for a panther but then again I never searched. I do have one for the King Tiger,.....and it wasn't cheap. Super King by David Parker. Man is it comprehensive. I have the kit so it will be right beside me when I get to working on it. I have an old Osprey book (Panther and its variants) that gave me a poster that had a cut away Panther. I saw a book by Ammo of Mig that is called Panther Visual Modelers Guide on ebay. It says something about interior. I know it is a paint company so they would be touting the use of their colors (I have several....lol)
