Potter Mellen Pewter ID ?

I have a pair of what I think are vases maybe candle holders , I think I just smelled candle ?
One is marked POTTER MELLON with an Indian (?) Arrow Head ?
They are 7" wide, 4 1/2 front to back, and 3 3/4 high .



I can't find much other than articles about the store in Cleveland , Ohio .

And only a handful of pictures of pewter .



I'm hoping someone can tell me more, if not were I can find more information .

 

Oak leaf?

 

This sold one is being called a planter: Scroll down to the SECOND image!!

I was trying to find the connection between Potter and Mellen with silverware and jewelry since the pewter items above did not seem likely. Lo and behold, here's Mr. Potter -
