Others are specific to Arm, Navy, Air Force and so forth. These were obtained from an estate of a Military Col, passed away in the Mid 20-Teens.We know very little about them. I have no knowledge of the Materials, Compositions, or even what any one was given out for or why. They Look Great and I hope they add value to your collections and lives.
