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

    The ammeter is made by Weston Electrical Instrument Corp and is model 322. See www.radiomuseum.org/r/weston_322.html

    Thanks https://www.flickr.com/photos/richardarthurnorton and https://www.flickr.com/photos/[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.
