Info about some (ammo)boxes

[PotatoDigger]

Hi all,
I am contemplating buying this lot of equipment and boxes, but there are a few items that I am not sure of what the are.
If you know what they are please comment, I'd like to know what the big box on the left and the small black box on the field bed are as well as that the small metal boxes next to the big box on the left.
The rest I think I know, but I might just aswell list it here:
-M35 or M40 German helmet (possibly battle damaged)
-2 sFH 18 ammo boxes (for 2 shells each)
-German Feldspaten
-unknown spade (allied maybe?)
-aluminium jug maybe Luftwaffe
-field bed (maybe US or German)
-KwK40/StuK 40 ammo crate
-9mm Parabellum ammo crate
MG34/42 oil can box

Any thoughts and opinions greatly appreciated!

Everything seems ok but why are three doorstopers

I think those are powder charge containers for artillery Raul

Oh. I think my grandfather has one of those near his front door

The big box is for the sight mount off a German field gun

Thank you for that info, kradman!
Do you have a photo of one in better condition by any chance?
