Catalina Pottery/Gladding McBean/Dorr Bothwell Somoan Design??

I have a Catalina Pottery stamped dish/tray that I can identify by stamp on bottom, but also have items that match dish/tray that have either no mark or can't identify. I believe that may be Dorr Bothwell Somoan design, but not sure. I think 2 pieces might be candle holders and one is a planter.  The dish/tray is Malanite Clay with a blue/turquoise glaze. The other pieces appear to be made of same material. Other than the dish/tray, I have looked online and haven't found any pieces the same as mine. The pieces were my grandmother's and were purchased in the late 1930's or 1940. Any help would be appreciated.
