Up For Sale New, Old Stock MOTOROLA Aircraft/Aerospace Round Glazed Heavy Double Paned Glass Panels. On each panel is written: 361C 7405-2 MOTOROLA  APR 11 1957. This item is a military collectors dream. We have done extensive research to determine exactly what these pieces are for and have not be able to fully nail down their initial purpose. We believe these to be part of an old aircraft super high frequency panel antenna that was mounted on the fuselage, but these beautiful historic pieces can be used for almost anything. Panels have a mirror-like quality as we tried our best to show in the photos. These glass panes were shipped from Japan to Dover Air Force Base to Warner Robins AFB (Georgia) in early 1981. From there they probably sat for nearly 45 years until we obtained. Each panel is 2.5 lbs with a diameter of 11.250" and .250" thick. There is some shelf-wear on a few of the panels (smudges) but otherwise extremely clean.
