Music Master Radio Reproducer

 I thought it was a fake antique! It is a real speaker that would attach to a radio. It was made sometime between 1924 and 1926 by the Music Master Corporation, 10th and Cherry Streets, Philadelphia, Pennsylvania, previously called Geraco and General Radio Corporation. The bell is made of mahogany strips and it has a heavy base of iron and the driver seems to be aluminum and steel. Retailed originally at 35 US.

One for sale for 1595!

Interesting article about getting it to work with a modern amp by increasing the impedance to 600 Ohms
