Weller Teakwood Jardinierre

Hi, I found this at an estate sale last year sitting out in the mud with some dead plants in it. I can't believe it didn't freeze and break over a Pa. winter. Well, I cleaned her up and started to research. Finally I put a pic on my phone so I had it with me all the time. I showed it to different dealers and collectors and finally one said he thought it was Weller.Well. I still couldn't find it so I bought Huxfords Encyclopedia of Weller pottery and low and behold on page 108 it's in a black and white factory photo. But that's it. No more info. It would appear to be quite rare. Can anyone fill me in a bit? Any input would be greatly appreciated.
Thanks, Brian
