Old pole supporting primary voltage lines somewhere within Jacksonville, FL municipal utility territory. I found this and a similar image (It accompanies this one, click "Previous") online and I do not know who took these pictures or when. Most likely these blue strains were made by Ohio Brass, maybe in the 1930s or 1940s? The brown box-type cutouts were manufactured by the Line Material Company; they are missing their bakelite pull-open fuseholder doors.
