Silver baby cup maker marks

Is there someone out there that could help me with these marks on the bottom of a silver baby cup. Not really sure where they're from. I've looked in several forums and googled everything I can think of. I still come up with nothing. I think they are from around 1929 to 1935.

Welcome, Tim.

What country did you find this cup in? Have you had it tested for grade of silver?

What do you make of that letter on the right? E, C, something else?

When I see a silver piece without the word sterling, and no known foreign marks, I assume it's "coin" silver or silver plate.(in that order, except that you have said you think it dates from 1920 to 1935, which would rule out coin in general. Why do you have those dates in mind? A family piece?)

 

That little fishy thing in the center resembles a Hans Jensen mark.

Oh found it. They say Hans Jensen with probable retailer or importer marks. Not sure if they have the photo right way up or not.

I knew I had seen that fishy before! And it is silver plate.
