eapg celery vase help

Hi everyone. Sorry about the photos...these Georgian optic style patterns are hard for me to photograph. Tho' I have somewhat improved since nearly a year ago :) This is a mid to late 1800s celery vase that I would love to narrow down to a specific manufacturer. It stands 8 1/2 in tall and 4 1/4 wide. Simple yet popular honeycomb or "Georgian" pattern. Three rows of honeycomb (none are perfect diamonds) with a faceted (fluted?) stem. I'm thinking either Mckee c.1897 or Bryce Higbee "New York". Any ideas? Thanks as always :)
On a related note...does anyone know of a reliable source of info to differentiate between the Georgian patterns made by Viking/Paden city/Fenton/Cambridge...etc? I have heard Fenton's tumblers will stack well and Cambridge tumblers have a row of perfect diamonds in their honeycomb design. Any thoughts on this as well? Thanks :)
