Here is a brown porcelain strain with the original wires attached. It is embossed SEN/SORY to the left, and IIECO/3017 to the right. (I've seen this embossing referred to as "HECO" in other postings of similar pieces, but there is no semblance of a crossbar to make the "II" into and "H" on this one.) The minor wire groove chipping is visible in the photos. Inquiries welcome.
