Pottery - USA Brush ?

Good Morning - Picked this little bowl up in NC. It is about 3" tall and 4 1/2" across the top. One of the pottery groups said Brush but I am not sure about that. It has some age to it. Another mystery to me. Thanks for any guidance or direction.

I don't recognize it as either Brush or McCoy. These beehive pattern mixing bowls are tough to ID. Just about every US pottery company made a version. Perhaps someone else will recognize it.

Thank you, as that is my feeling also.

 

You might look at Robinson Ransbottom to see what you find. I don't think they always marked their items.

 

Thanks Clutteredcloset, found some vintage RRPC with the glazed bottom and dry foot/ring as my piece has and I feel this is at least on the right track! Plus the clay was pretty much spot on.
