U | 1,015,224 | January 16, 1912 | Insulator Suspension insulator of insulating rope, hoods, and arcing rods. [This looks very close to the handful of glass suspension insulators found in 2002 in northern CA by Paul Greaves and Mike Spadafora. The glass was most probably made by Hemingray. No markings were found.] |
