Outlet American International Airways / Kalitta Airlines Stewardess Vintage Wings Pin

This is a very hard-to-find original uniform pin from American International Airways. I believe the company started in 1973 as Kalitta Airlines and then the name was changed in 1984. This was most likely a pilot's or stewardess' pin. Since this came out of an estate of a former Pan Am stewardess / purser, I'd assume that it was a stewardess' pin since it belonged to her.

It measures 2" long and is in excellent condition. There are no markings on the back. I don't know what type of metal it is. At the minimum, it is a heavy gold plate. This was a small airline with only a few planes and finding anything from outlet them is fairly hard.
