[Milsurplus] "1917" Trench scene, revisited

[Hubert Miller]

When I saw "1917" a year or two back, I was puzzled by a sign posted up inside the 
abandoned German trenches. It went by too fast for me to register what the exact
words were. I really thought I'd sent to this group a screen snip of that movie scene,
but I fail to find it, so apparently I watched enough of the movie again to see this
part, but didn't grab it.
This wooden sign, I guess about 18 wide by 14 tall inches, read

1 Gasfächer
1 Eimer
1 Stange
1 Spaten

This means: 1 gas fan; 1 bucket; 1 pole; 1 spade. I surmise this was for removal or 
burying of spewing gas shells?
Olde business, but I'm getting it off the books at last.
