We went through and rebuilt the set over the last few days and it appears to be all there including the minifigures and accessories. Please see photos for what is included and the condition. If for some reason you do find that a piece is missing when you are putting the set together just let me know as I likely have the piece in the Lego pieces that we have and I will send it to you.
However, we went through it pretty carefully and it all appears to be present and accounted for including all of the hard to find accessories. Any questions please let me know.
