OK...
It was introduced with the rest of Philco's lineup for the 1932 selling season.
It was intended to connect to the output of a Philco radio of the time.
I have never seen any documentation on this unit other than mentions in 1932 Philco sales literature. I have never seen any other documentation on this speaker.
