1939 Eisernes Kreuz- authentics?

[SoldadoRaso]

Hi

I have seen a store that sells these 3 1939 Eisernes Kreuz. None have markings. I would like to know if one or all, as the seller claims, are original.
Can somebody help me?
Thank you so much

Thank you very much in advance and a thousand apologies. If they have manufacturers' markings, you can always consult them on several pages, but those that do not have them give me a lot of respect.
