content: Marked: "Western Electric / Made in U.S.A. / 1-A / 2740". A rectifier tube with circular loop electrode and two stranded copper leads. No base. Bottom-tipped G-shaped envelope about 80% silvered with one lead wire embedded in the coating. That lead passes thru a separate tip mounted on the side of the tube. A window in the coating faces the plane of the loop electrode. This unit appears similar to the GM type 76 photocell (catalog #322514).
