This vintage Farberware stainless steel electric skillet fry pan model number 310-B is completely immersible. It's 12-1/4" diameter by 2-1/4 inches deep and has both long and short black side handles and a 3 inch high dome lid. The patent number on the bottom dates to 1966, so it was probably produced in the late 1960s or early 1970s.

The skillet works well, has no dents or dings (just a few storage marks on the lid and shallow, short utensil marks inside), and is clean and shiny other than around the bottom ring. The metallic label on the handle is faded, likely from cleaning or dishwasher use. I have trouble getting even heating on my glass stove cooktop with any pan larger than 10 inches, so a big electric skillet is like this is a must for me.
