This is for two fairly near-complete sets.  Both sets are near-complete minus most of the minifigs. 

I used the parts list on toysperiod.com, and all the missing parts or replacements are listed below.   Condition on the parts is excellent, with very decent color.  Both manuals are included and pretty decent.
