This is a VINTAGE, unique combination of a jigger and a mixing spoon. The bar tender can quickly measure, pour, and stir any combination of drinks. Touching the spoon to the bottom of the glass allows the contents to pour down the spoon - THIS WORKS! I have seen another (nearly identical) with a sterling silver, marked spoon. I doubt the authenticity of that one. This is unmarked and silver plated. The exterior jigger plating has long disappeared, from years of use. A much later item by Napier, of the 1970's was probably copied from this one. Measurement is made in 1/2, 1, 1 1/2, and 2 oz. increments. Length is about 9 3/8" and silver plating remains in the interior of the jigger. This will be shipped at the 2# Priority Mail rate from zip code 91436, domestically.
