The one piece that i'm sure is missing is one of the pieces that's used two detach the main rocket. You can see it in the second photo. Other than that, i'm not sure what's missing. However, the box and the manual are in great shape. The original owner did not slice the seal tape. They just gently removed it. The 13 photo shows how much I will be disassembling this set for shipping. I cannot guarantee if it will be intact like that, but I will do my best with generous packaging.
