There are two instructions manuals. One for builds A - K, and one for builds L - O. The differences between builds is slight, and spans beginning to end. I didn't receive any PE parts, so be sure they are there. There's also lots of little bags with parts. There are sticker masks for the canopies. You can barely make out the id's on the four sheets, but they are there. You can build with Bombay doors open or closed. Open only shows six 500 lb bombs only. Because there are so many build options, there are a ton of decals. Stencil decals are plentiful as well. I ran into serious fit issues at the top and front of the plane. In my opinion, this limited edition kit is not worth the cost.
