I would like to ask you, the experts, if you could, please, tell me if these things can be from ww2 Engine-generator. They were found on the field on battle and the initial hint was that it would be coming from ww2 Engine-generator. Given that I am not very familiar with how the parts of the ww2 Engine-Generator should look like, I would like to kindly ask you for the confirmation or rejection of the initial information.

The size of the plate is 14,5 cm x 16 cm.

Thank you very much in advance
