Modernist mid century Farberware chef fry pans...aluminum clad stainless.
these were made in 3 sizes, that I have seen... 8" 10" and 12" diameters... the 8" is the most common - a nice omelet pan.... the 10" is not so common... and the 12" is quite rare to find. I have only come across one 12" in twelve years selling vintage cookware.
I love the handles... very modern and sleek... they fit the hand well. The attachment is stylish in an industrial design sense as well...
