I found the same marks on a Louis Seize-style creamer, imported to Sweden in 1925.

and the marks of the sugar bowl

And here is the set
The sugar bowl had the ”swan over shield mark" of Vereinigte Silberwarenfabriken of Hanau.
It was founded in 1914 after a merger between Gebrüder Glaser, Hanau and Wolf & Knell.
I assume that this set is produced by either Gebrüder Glaser or Vereinigte Silberwarenfabriken of Hanau.
