Propeller (airplane) Lapel pin - this is a great pin for anyone who is into aviation. The pin features a two blade propeller and is popular with pilots. Recenlty, it's become an icon of drone pilots! Cast in solid pewter with a hand satin antique pewter finish - this pin measures 1 3/8" long and comes with a standard military clutch (aka butterfly clutch) back. Proudly Made in USA
