Old piece comes from an estate. It is hard to read, but I believe Pat. Pending is marked on the bottom. There is a large chip on the side of the bottle. There are also small chips. It measures approx 2.75 inches tall x 2 inches wide on the bottom.  I do not if there was a finish sprayed on the bottle it could be a possibility as I washed it and there was a little sparkly residue on my fingers.
