A.W. Bowman Loose Coupler for Radio Reception
This is a loose coupler, most likely distributed by Sears. It is assumed it was made by A.W. Bowman since they made many wireless items for Sears. The label states "Licensed Marconi patent 763,772". It is the same label on the Sear/A.W. Bowman crystal detector shown elsewhere in this site under wireless.
