Here is a Douglas Aircraft badge with 10 yr pin, 15yr pin on the Badge is says Norma Prince (RETIRED).
The 10yr pin is 1/10 10K GF (Gold Filled)
The 15yr pin is 10K yellow gold with 3 diamonds on the globe.
There is also a VIP Douglas Aircraft pin with a Light blue enamel back ground.
The VIP Douglas Aircraft Pin is not marked, so I have know idea what type of metal it is made of.
These retirement pins where from a member of my wife's family. Best estimate is that they are from sometime in 1970's or early 80's.
All the pins are in excellent condition.
Please ask any questions you might have. I will be glad to answer them.
Thank you for looking.
