Brass Inkwell Carp Fish need maker Germany?

This ornate Inkwell is made of Cast Iron and was then Bronzed. The pattern is fish and leaves with openwork around the edges. two Original glass Ink pots with no chips or cracks.

The measurements of this piece are 10"long, 7" deep and 4" tall. on the back in the valley between the 2 orange dots is some writing, which I cannot make out. Any help? Age has started to deteriorate the piece and the initials or lettering cannot be easily made out. Suggestions? Thank you so much
