RYAN Aeronautical LOGO AIRCRAFT Pin NAVION CREW WING

Description

Ryan Airlines of San Diego, CA...the folks that brought aviation to America's imagination. Charles Lindbergh had Ryan Airlines build "The Spirit of St. Louis" for his transatlantic flight. These pins are obviously later but still mighty cool. Ryan Aviation became part of Teledyne
in 1969, and then Northrop Grumman in 1999.
I believe these are lapel "crew pins" each seems to have a serial number on the back. They appear to be enamel over gold-tone (probably brass.)
Please plane aficionados, if you know more..tell me! My dad was an airplane NUT, building models back when Lindbergh made his flight! I'd love to know more.
