set is missing 10 parts, 7 have been replaced and 3 are completely missing. the 3 that are missing completely are; 1 minifig head, large blue slanted piece and 1 4x2 flat. Going in order of my pictures, I'll state which have been replaced. a 1x4 brown flat has been replaced by a grey 1x4 flat smooth. a 2x16 flat red has been replaced by a 2x5 and a 2x10 red flat. a dark grey 1x2 has been replaced with a dark grey 1x2 that has a hole. 2 red 1x2s have been replaced by 2 black 1x2s. a tall dark grey flat arch has been replaced with a shorter light grey flat arch and a 2x1 brick. a blue 2x1 with a hole has been replaced with a red 2x1 with a hole. the next to last pic shows the missing 2x2 flat smooth tan that should be inside the mechanism.
