As a followup to yesterday’s Newcomb Pottery post, the photos below provide visual examples of various date marks. 
BY39 corresponds with a Newcomb pottery production date of 1907.
ES26 corresponds with a Newcomb pottery date of production of 1912.
HA80 corresponds with a date of production of 1914.
IC25 corresponds with a date of production of 1916.
KY61 corresponds with a date of production of 1920.
SA67 corresponds with a Newcomb pottery date of production of 1929.
Below is an example of the rarely seen Newcomb Pottery paper label. The NL85 date code indicates a 1923 date of production.

I have something that looks like HUIS on the bottom of 1 of my 2 vases. There is a name before the HUIS, but I can’t make it out. Also, the C with a V in the middle. Could the HUIS be H U 1 5 instead of IS? Any help is appreciated.
I would have to see a photo to be sure but if the vase is Newcomb pottery mark could be HU15.
