Another gem from my private collection of vintage microphones. There isn't much information about this one in particular because it's very rare, perhaps a one-of-a-kind... it even seems to be made of CATALINA... precious material for making prestigious American radios... if anyone knows the history of this item, please let us know... the item is new (unsold stock), never installed... if you're a true collector of these items, you can't help but own it...
