Amazing Mid-Century silver plate cylindrical cocktail or Martini shaker by silversmith WMF, Germany. Three-sectioned designed cocktail shaker with removable cap and strainer. Lovely streamlined geometric shape, typical of the Mid-Century Modernism period. Marked underside with legal silversmith hallmarks reading NS - WMF.
"NS" means Neusilber (Alpacca,) which is an indication of a base metal for silver plating. The company used this mark between 1918 and 1965.
