Vintage Milk Glass Shell Fish Dish

Vintage shell bowl with a dolphin/koi fish base~ I think that this is Westmoreland, but it is not marked. I have heard that earlier pieces are not marked, but I'm not an expert in glass. It almost has to be Westmoreland because it is exactly the same as the marked pieces that I have seen listed. It is in excellent condition with no chips, cracks or scratches. *measures approx. 8 x 6 3/4 x 6 ~ it weighs 1 lb 14.4 oz Contact me with any questions. I also have other vintage items for sale and will combine shipping. Thanks! Lots more milk glass for cheap! Bundles
