Vintage Industrial pendant white lamp - 1960s

This industrial pendant lamp in white enamel with a heavy cast iron suspension and rare glass jacket evidently originates in Hungary, probably 1960s. It was thoroughly cleansed and professionally re-wired (textile-jacketed cord in black and white). And of course, there is the obligatory patina that we adore so much. Measures: diameter 34cm, height 24cm, cable length/ chain 150cm.
