Help with ABP Cut/Engraved Compote/Tazza

I have this small Engraved Compote, or Tazza, that I have been unable to identify. It stands 6" in height and is 4-1/2" in diameter. I am leaning toward it possibly being H.P. Sinclair due to the ring of small ovals around the base and lower part of the compote. Beyond that I really do not have a clue. The center of the oval "suns" or "flowers" is more deeply cut and polished. I do not have access to Cut/Engraved reference material other than searching online. Any thoughts appreciated.
