unknown mark on probably south German spoon

[R ingo]

Hello,
has someone an idea about this spoon and its marks? The spoon probably was made in southern Germany.

Kind regards,

Hello,
I have two questions to the experts in southern Germany and Swiss.
The unusual transition from the handle to the bowl seems to be not very often. Does anybody know where this was usual.
I have tryed to reconstruct the city mark. The tree-looking makers mark is surely a "M". Has anybody an idea, what city it could be?

Kind regards, Ringo

I am having computer problems, and can't access my files, but in the meantime could you post the two marks with the assay squiggle in between in one photo? I read the first mark as OS, CS, or something similar.
