Here's an STC 4021D Dynamic Microphone from the 1950’s! This particular 4021D has a Vitavox B50A element inside. As I've never seen a "D" model before, I'm unsure if it's original or not but it has a similar sound to a normal 4021 with a crisp high end. This microphone has some medium wear, especially to the top baffle but works perfectly. This one comes with an original connector setup that was likely used for broadcasting back in the day. Grab this rare modded 4021D Dynamic Microphone from STC!
