I just found this while slacking the day away on youtube.
I know the prop, but hadn't seen this vid before:
https://www.youtube.com/watch?v=imGWFzEEjuII think it's more proof that the old Humbrol 170 used on the props probably wasn't the recent reddish brown Humbrol 170 mixture the community thought it must've also been back in the day.
For Humbrol 170 the "formula" obviously changed.
Here, too, it shows the prop to be on the more OD side of things. More in kinship with RAL7013.
Also, it's just a great display of the prop and shows how cleverly they did it for the close ups in the movie.
Edit:Oh, and also: bonus GB2 Ghost Trap!
