Vintage Wheaton (which was originally out of Millville, New Jersey) salt dip, showing a bird and nest on a branch.  The nest is the salt dip/cellar.

You could also use it as a ring dish. 

Beautiful green color.

Texture makes it feels like the roughness of a branch or tree limb. 

Marked with a W with circle around it on the bottom of the next. 

3.5 inches long in total.
