Are these marks Hanau or silver-plate?

[AllSeasons]

I came across the marks below on an item that I may be interested in. I'm not entirely sure what these are. They might be Hanau, but they seem more like silver-plate marks to me. The left one seems like an export or duty mark; the middle one looks kind of like a lion, but more like a ram; the right one looks kind of like a Sheffield crown. I'm leaning more towards silver-plate. What sayest the forum?

The image is below. Thank you in advance.

Hi,

It's a mark we've seen many times on the forum, always on plated items.











Hopefully your post may prompt an answer from someone.
