Parts for id

Hello, recently, while walking in the forest, I came across a place with a lot of such elements. Unfortunately, I don't know anything about aviation. However, I am very curious about these elements. Is anyone able to identify what country this plane was by the rivets and maybe the exact model by some of its elements? Sorry for any language mistakes

Welcome to the site. I do not recognize any of the parts but those who might be able to help may need to know what country your forest is located in.

Near the eastern border of Poland.
There are stories from local people that it was a German Ju 88 plane, some say it was a B17 and others say it was a Mesershmit
It is possible that it was a B17 because one crashed in 1944 on June 21 after bombing the refineries during Operation Frantic.
But I'm not sure because my friend says that these elements fit the German plane
