A tent stake?
looks like a shovel and a tree branch…;>)
Too straight and rusty-looking for a tree branch.
I can positively state, without equivocation, that it is, indeed, definitely, a shovel.
As to the dark thing next to the shovel…?
For me, I have seen german barbed wire posts that they would rest it onto something that looks like that. BUT they were like 3 feet long.
I meant to ask, how long and wide is the unknown thing?
Can not judge size by the shovel.
It looks like there’s a bolt knob sticking out (to the right side) near the top of brown area.
