Some blocks have signs of wear from play. From what I can tell the set is missing part 3069p25 Light Gray Tile Black Buttons Computer Pattern, and a space fig (Sp037).

Lego has been cleaned.  Additional cleaning left to buyer.  I don't want to damage the Lego.  Set is in used condition and does have flaws.  

Lego is shipped disassembled.  No manual and no box. Instructions can be found online.  Set is Incomplete. 

Any questions please ask.
