Gross Star Electric Iron AC-DC

A very early electric iron circa 1920s as it is AC and DC powered. DC went extinct in the early 1930s as far as power to homes. This was made by the L. Berstock Company.
This iron is even heavier than the sad irons as it weighs over 12 pounds. And very large at 10" long. It has three heat settings. The cord is a bit rough so I am not going to be plugging this but I will note be replacing the worn but vintage cord.
