Last shot of the element. Before I finished uploading these I had my answer, from both Bill Ostrander and Doug Moody; one was a link (enclosed below) with a pic of how it was used, and an explanation that they were used as a reflector heater, screwed into a trouble light like fixture. See the pic at the link below, and thanks to one and all!
