This is a beautiful mint condition Asprey & Co cocktail shaker and it is marked on the bottom as such. It is the Barbell model with a very functional shape for shaking cocktails. It must be a pretty early model since the bottom is stamped patent pending along with Asprey London as shown. It has no flaws, dents, wear etc. the inside has some discoloration from drinks made but otherwise mint in every way, very unusual for a shaker this old from the 1930’s!
