LEGO Space: Alpha-1 Rocket Base 483 & 6875 & 6820! Half Sorted! Please Read!

This was a project I thought I would enjoy and did not. It is a mixed box of multiple sets including the ones mentioned in the title. I have started and quit multiple times in attempting to put these sets back together. I have no idea how complete any set is. They do come with some mini figures/accessories to the mini figures. All manuals/directions have heavy wear and damage. Please see pictures and let us know if you have any questions!
