Turner / 3M 78-9020 Dynamic desktop mic
Very stylish brushed metal desktop microphone, made in the USA by Turner for the 3M brand.
(I have another in my collection with the Turner badge).
Working well. It has a mind-bending number of switches – you can either latch it on with the lever, or press the button on the front, or it can switch on when lifted off the desk! And can be set for push-to-talk, or push-to-mute.
This would make a great talkback mic on your studio desk. Just make sure it’s not on when you think it is muted!
