This Platinum Edition of Revell's Tirpitz is mixed media of styrene, wood laminate deck material, and photo-etch. Overall assembly went quite well, but curiously enough, much of the photo-etch was not called for in either of the instruction manuals. (?) Watch plenty of You Tube videos of this kit before beginning assembly, as they can save you a lot of headaches. The Platinum Edition is very challenging, and I recommend it to experienced to advanced model builders.
