Matte White Art Pottery Flower Form Vase Mystery McCoy Zanesville Niloak Help Please

Hi there,

I appreciate your time. I'm trying to identify the maker of this very old matte white art pottery vase.

I mainly collect McCoy, Zanesville, and other USA pottery pieces made between the early 1900's and the early 1950's. I am stumped on this one. it has tiny pin firing marks on the bottom and no maker's mark.

I wondered if it was may Camark or Niloak, but no luck.

Your help is appreciated!

Thanks!
