This is a super rare Brush B-1 microphone from the 20s-30s. Brush Development Company invented the piezo-electric crystal and licensed the technology to many contemporary mic manufacturers, but made few mics themselves besides the B-1 and some other odd ball shaped mics. This mic has not been tested, and it does not come with the stand.
I love microphones and hope you do too. These mics are surplus from the Paquette Museum, the world’s largest vintage microphone collection. Take a look at other items in my eBay shop. Feel free to contact me with any questions. I will be posting many items over the next few months so keep checking back.
Price is for mic as-is. I use USPS for domestic shipping. I do not ship internationally at this time.
