With reference to the Bovington site, there's an excellent book on the Tiger, and to the best of my knowledge it's available only through their gift shop. The title is PzKpfw VI Tiger I Tiger 131 in Pictures. It features literally dozens of excellent color pictures of the museum's restored Tiger I, including interior and engine compartment pics. This book isn't cheap--12.99 pounds, which at the current exchange rate works out to about US $25.00. However, all profits go to back to the museum, so you can take comfort in knowing you're supporting a worthy cause.
I picked up a copy when I was last there and have found it to be an excellent reference.
