RCA vintage microphone MI-6228-M Untested. I added this mic to my collection a few years ago. It is time to reduce the collection. I have never tested the mic and was used only for display. The mic and stand are in very good condition. There are a few small chips. The screen grill is straight with no bends. The grill cloth is near perfect. It looks original with only one pin prick, very hard to notice. The original stand base has rub marks, the vertical portion of the base is near perfect, no marks. The cork bottom is in very good condition. As per the very very small original decal on the bottom of the mic, behind the cable connector, MI-6228-M, HI-Z impedance. Do not confuse with the M-12017, a much more common RCA aerodynamic mic. No shipping charge.
