Please help to identify WWII airplane bonnet

[floriana]

Dear Collectors,
please help to identify this airplane bonnet. The seller told me it is a airplane bonnet from a German airplane Stuka. But I do not think so. Can anyone help to indentify.
Sorry for my bad english, but I´m from Germany. The size is around long:1720mm rear width:950mm ,front width:760mm,height rear:590mm and height front:340mm.
It is made from aluminum.
many thanks Stefan

Are there any numbers to be found in it? ( if it is german it surely will have some.)
