Is there a complete interior for a KT Porsche? I will be building the Dragon kit.

THe only KT interior kit that I know of was produced by Jaguar and it was for the Tamiya Henschel KT. I don't know if it's still in production.

Assuming that you mean the P2 Turm fitted to the first 50 Tiger B hulls, I am not aware of one but the Jentz & Doyle book on the Tiger B (VK45.02 to Tiger II, published by Schiffer) has some internal drawings of it.

Unfortunately the only surviving turret (at Bovington) is pretty gutted inside (last time I looked, the gun as supported on some concrete blocks!) but most of the innards (at least as far as is visible on a model) are likely to be similar to those ofthe Serienturm.

David Parker did an excellent build of Trumpeter's 1/16 Serienturm kit in AFV Modeller a couple of years ago (and on a website) that would no doubt be of use too.

By searching images on google under David Parker King Tiger , I found these..theres more on the net.
The following link will send you too a photo album of someone elses 1/16 project.
Good luck Matt.
