Flipping through examples of Victorian meerschaums, I found a similar coat of arms for “Frank Weiss, Vien”.
It had the griffins rampant on either side of a shield and a crown or helm on top of the shield, but instead of the monogram inside the shield it has the Austrian two headed eagle.
What they have in common, though,seems to point to Austria, possibly Vienna..
However, even if I’m correct about the hint leading to Austria, I could still be painting with a fairly broad brush because we’re probably talking about the heyday of the Austria-Hungarian Empire and that covered considerably more real estate than the Austria of today.
