Vintage Astatic D-104 "lollipop" microphone for use in CB Ham radio. $30. Not tested. I have no way of testing whether the microphone elements work but replacement elements are out there to buy since this was a very popular microphone model made from the 1930s through to 2001. This one has a 5-pin connection. I do not know what type of connection this works for. It has a T-UG8 stand which means it has a preamp and need a 9V battery to operate.
