German or Dutch marks?

[AllSeasons]

Sorry for coming to the forum for yet another set of marks that I do not recognize, but I guess this is how I learn. I have to admit that I don't know where to start with these marks. Maybe they're Hanau, but I couldn't find anything like it. I think the mark on the right may be an import/export mark? Not sure at all about the other two marks. Any insight would be appreciated.

Admins, please kindly move to the right forum as appropriate.

The images are below. Thank you in advance.

Hello, we might need a sharper image of the marks. Regards, Bahner

Thank you. Does this help?

Hi, I believe it could be silverplate marks.
