Help ID Green Man or Silver Gargoyle Brooch 800?

I can't figure out the letters. I thought maybe Marius Hammer but it's not quite a match, although the stamp looks like it's not complete. Also, is this a Solje? And is it a Green Man? And are those swan heads or snakes? Thanks so much for taking a look! These boards are always so informative.

I think I've figured this out after looking at every photo of Marius Hammer hallmarks on the Internet. It does look like the central part of the signature and the swan heads are definitely snakes. I am also thinking maybe it's 830 silver and also that a Solje/Solge isn't always for a wedding, although I'd like to be invited to the wedding where this brooch is worn!

Any other thoughts I'm always appreciative of learning.

Thanks!
