This is a vintage Liquid Core stainless steel electric skillet. I believe it was made by West Bend. The lid has an L on the black bakelite knob. The base is marked Liquid Core Stainless Steel Electric Skillet Cat. N. 92010 1200 Watts 120 Volts AC Only 93 13 E19762 Made in USA. The skillet is in excellent condition. The electric cord has a bit of wear, the rubber is slightly heat damaged in one spot about 1" long. It is still safely covering the wires. The skillet is 11 1/2" wide at the base and 13" wide at the top.
