Comments.Text: Thanks Alex. Have you got a tool for finding sets that contain a list of pieces? I've seen Rebrickable's API but haven't gotten around to writing any code against it. P.S. you should write that as an answer so I can mark it as correct

Comments.Text: Is it me or are the transparent blue parts different colours? Looks like the [1x2 plate is Transparent Blue](https://brickset.com/sets/containing-part-4260426), while the [1x4 tile is Transparent Light Blue](https://brickset.com/sets/containing-part-4586557)? In which case only [2016 LEGO City Advent Calendar](https://brickset.com/sets/60133-1/City-Advent-Calendar) contains both, and that's clearly not right.

Comments.Text: If you combine the black 2x4 slope with the 1x4 tile the best fit is 70228 "Vultrix's Sky Scavenger", but that doesn't have any transparent grey slopes in it.

  ### Answer by username_1 on 2017-09-10. Score: 3
  
  You could cross-check the sets with the [transparent 1 x 4 tile](https://www.bricklink.com/catalogItemIn.asp?P=2431&colorID=15&in=A) and the [transparent 1 x 2 plate](https://www.bricklink.com/catalogItemIn.asp?P=3023&colorID=15&in=A). No matches jump out at me.
  
  Unfortunately, I don't know of any tools to make crosschecking easier.
