Comments from Submitter:
There is no black 8-Axle in this set.
I have this set and confirmed it inventory from sealed set content.
There is in this set black Technic, Axle 8, I have it in my set. It is also on
parts list in instruction and it is needed to build model B (this part is not
use in main model)
