The Ellis Microphones were made by Ellis Electrical Laboratory Incorporated, Chicago Ill. The only microphones I could find them making were the Spring Carbon Microphones out of the 1920s and 1930s. It appears they also made a stunning tall microphone stand.
Some of the model numbers include the 29N and the 30N carbon microphone. These were the 2-button or double button carbon microphone types.
I share a passion for collecting all things vintage and antique and love to share that passion with others.
