Midcentury Brown Speckled Pottery Creamer

A classic and charming little creamer pitcher. Vintage, probably midcentury. Diner or restaurant style. There is no mark to show who made it, and I have searched at length for identification. I only found one other picture that matches, in a set including sugar bowl and teapot, but they also did not know the origin other than saying "midcentury." There are no chips or cracks. What appears to be a chip on one side of the bottom is actually glaze that flowed down over the bottom edge. There is some very very faint visible crazing in the finish, which indicates age. 3.5" tall x 6" wide (including spout and handle) 3" diameter opening
