The B-17, B-24, and B-29 are from the mid Seventies and are all 1/48. The B-36 is 1/72. Mine came with Shep Paine's diorama guide and the decals for Enola Gay and Bock's Car. Never finished mine, don't know where it went. One thing I do know is you're going to need weight, and lots of it. I look forward to your build.
