German 800 silver bowl

[AllSeasons]

I just purchased this 800 bowl, but am having trouble tracking down the maker/silversmith. The mark appears to be a dot inside a circle. The closest I could find was Weinranck & Schmidt from Hanau. Any insight would be very much appreciated.

The images are below. Thank you in advance.
