RING SPRING CARBON MICROPHONE. This type of mic represents some of the earliest forms of voice transmission technology. It’s most likely from the 20′s, and is a carbon “double-button” NOS element spring mounted with a 6 steel suspension ring. The element looks to have never been put into service, chrome looks new with no aging evident. The ring is mounted to a holder that looks like it could be interfaced with a mic stand, although some fabrication may be required on the mic stand fitting. The mic stand fitting does not have threads but would slip over a stand riser and tightened down with a screw bolt. I INVITE YOU TO CHECK OUT MY OTHER VINTAGE MICROPHONES FOR SALE.
