Azmyth Recording acquired this RTL 630 microphone in an estate sale here in Indianapolis and we are looking for information on it. It has the call letters of a local radio station WIBC scratched in it. Seems it is at least a part of local history. Let us know if you have any information on this or other RTL microphones.
