Up for sale here is this rare vintage Airline 62-3100 crystal "sound cell" microphone, from the late 1930s or 1940s. This is a rebadged Brush B1 microphone, which is a very early, very rare mic. This is in extremely nice shape with light overall wear and a few scratches here and there, as well as a gouge on the bottom next to where the cord goes in. The cord is there but it is cut off on the end. This came from the estate of a radio station engineer.
I have not tested this, so I don't know if it works, though it probably does. Please see my pictures for details. If you have any questions, please ask.
