What periods do these mixers come from?

The pieces span the interwar years, with the vast majority originating from the 1930s alongside occasional examples from the 1920s and 1940s. All share the aesthetic hallmarks of the Art Deco movement, regardless of the specific decade of production.

Are these mixers made of solid silver?

Most examples are constructed from silver plate, electroplated nickel silver, or base metals rather than solid precious metal. Manufacturers applied a thin layer of silver over a durable core such as nickel brass. Marks on the body often indicate the plating technique or the manufacturing house.

How do I identify novelty cocktail shakers?
