    It appears to be a photovoltaic cell and a meter for measuring the power output.

    Thanks and[email protected] . I'm going to ask that we add a caption saying it's the Weston Electrical Instrument 322 and that it's a microammeter. If anyone can find an image showing another similar photovoltaic cell or a newspaper article I can add additional information.
