Yea a little stumble on my part last night. However wasn't German Silver the name for the metal made of Copper Alloys and sometimes Zinc, that was used as a base metal in plating. Actually called Nickle Silver?, which actually contains no silver? or when marked german silver is it just plated nickle silver?
As for the age of the piece I would just be guessing, these items have been popular from Late Victorian to even today, maybe a closer look into the hallmark may get some answers. When looking around the hallmark that you have is all I could find also. Not sure if they ever used other hallmarks. But if Ruby lane had a hard time find info on this company, I'm sure I will yield little better. Like always I love to guess anyway and I would place your item in the 1930's or 40's, Not sure it has the flair of Victorian or the Art Curves of the Art Noveau period, but the fancy the simpliticy to the 30's and 40's it does have.
