The pin is a U.S. Navy Command at Sea insignia. When worn above the ribbons on the left breast, it signifies the wearer is presently in command of a sea-going unit (ship or squadron). When worn below the ribbons, it signifies that the wearer has previously served in a command at sea billet. The markings on the back might be some personalized markings, or they could be manufacturer's marks.

Thank you for the explanation. The pin has extra meaning since this Navy Vet worked hard for his command. And the “B” on the back might mean that it was his second highest pin, with maybe one above his command pin.

I am wondering what to do with it. If I was sure that it would not get lost, I am thinking of putting it on our Olney Navy flag. The command pin has 3 pins on the back to attach it to a uniform. It should hold on the flag if I put it at the top by the pole.

And Thank You for your service.
