Comments.Text: 8285-2 model doesn't exist. "-x" naming is used for different sets with the same number or significant difference between versions of the same set. What you are dealing with here is known as "B-model" or "alternate model".

  Rebrickable [has an option to compare](https://rebrickable.com/sets/compare/slow/) set's main models and some of the B-models as well. However there is no inventory for second model for 8285 set available on Rebrickable. The best I could find is a [LDraw file available on Eurobricks](https://www.eurobricks.com/forum/index.php?/forums/topic/48285-key-topic-official-lego-sets-made-in-ldraw/&page=51&tab=comments#comment-2019924).

  I went through the 8285-2/alternate model instruction leaflets and made a list of how many of each part was used for the build.
  
  I only had a (quite bad) PDF from Lego's website, so it might not be 100% correct, but I thought that others might get use of it, so I created it as a custom list on Rebrickable (I'm not yet high enough level to submit it as an official inventory).
  
  Here's a link to the list: <https://rebrickable.com/users/username_0/lists/68485/>
  
  Here's a link to the comparison to the main 8285 model: <https://rebrickable.com/sets/compare/slow/?1-set=8285-1&1-inv=24316&1-user_list=&2-set=&2-user_list=68485>
  
  (I don't take any responsibility for the list's accuracy -- might be a couple of parts off...)
