Section of Plexiglass from German Fighter Plane-This section measures approximately 10 inches long at its longest point by 5 inches tall at its tallest point. It is clear, fairly thick plexiglass and it is in the shape of an elongated triangle. There is a section at the bottom where it fit into a channel. We are not sure exactly where this is from, but we know it is from a World War II German fighter plane. Cool!
