Findings from Monschau Forest

Hey Friends,

yesterday I was in the woods just to get an image of that what I´ve read in books.
Then I found the following things in the area I was in. I need not to dig, they were lying on top of the ground.

Can anybody tell me anything about these findings...?
I´ll put in some more pictures after cleaning.

Thanks a lot!

 

The item on the right seems to be the upper part of an U.S mess kit (plate)

 

Looks like a part to a field heater/ wood stove......the bent piece with the knob.

The little vial could be a rifle oiler.....is there any thing inside it?

 

Thanks a lot for your informations!
I have not managed to clean the items yet - so there are no new pics of them.

Yes in the vial is some plastic. A little stick is fixed at the cap. It looks like small round piece of plastic was fixed at the end of the stick - but now it´s loose. I can´t get it out of the vial...
