The LEGO Space Shuttle 10231 set is a used and incomplete building toy. It is a LEGO branded product that includes various LEGO pieces to build a space shuttle. However, some pieces may be missing, as indicated by the "incomplete" label in the title.

As far as I know it's the one black tube on the side of the shuttle where my pen is pointing that's missing and  also pointed out in the instructions with my pen in one photo

The little support vehicle is also missing

And three of the flood lights

Other than that I think it's complete

You will get what is pictured
