Vintage Inkstand

I love this inkstand, but its provenance is a real mystery to me. There are no markings. There appears to be an eagle with a helmet atop its head and outstretched wings in the center. A floral or leafy motif as well as a Green Man type face with a winged helmet atop his head also appear on this piece.

At the same place, I found an antique Villeroy and Boch sugar bowl (made in Germany) and was amazed to see a face with wings atop its head on the bottom of the piece. So, I wonder if this inkstand could be German-made?
Any musings on this piece (or outright identification!) would be greatly appreciated. Thanks for looking!
