There are three major penguin cocktail shakers. The Napier (well marked underneath)); the Restoration Hardware that separates near the middle of the penguin body, and this Penguin that is a 1930's original chromium plated Penguin Cocktail Shaker produced in the 1930s to compete with the Napier penguin. It has a screw-off knob for pouring at the tip of its beak and its wings are molded into the body of the shaker. 11 1/2" high. No dents or dings.
