RCA Badged Ribbon Microphone - Vintage 1940's

• I've never seen one of these before and have had it in my collection for a few years. It is a very old Mic, but to as it's authenticity as an RCA, I have no idea who made it. It is unique
• It has the The RCA Logo engraved plate on the front - No Model # 
• It is a standard type Vintage Ribbon Magnet Motor inside but has been converted to a newer low impedance transformer and XLR Cable
• If you a Collector, I don't think you'll see another one of these, I haven't
• It is working
• Mic Stand NOT Included
