Here is a photo of S.E. 13th Ave. in the Sellwood district of Portland, OR., looking north, taken ca. 1910. The double electric trolley tracks originate from a large streetcar barn complex about 3 blocks south of the photo. The street is unpaved dirt and in the famous Oregon rain became equally famous Oregon mud! The early style Portland Generel Electric Co. power poles display a hodgepodge of various cross arm types and placement on the untreated cedar poles. The top cross arm holds a 10,000 volt line that I know originated from the Willamette Falls powerhouse in Oregon City, 14 miles south. I also know that the insulators used are Fred M. Locke aqua glass CD 289's made by Brookfield. To see a CD 289 in use more recently in Portland, [id=227045522] Until last year, I lived in this neighborhood about 4 blocks from there for 30 years and the only things in this photo remaining today are the 3 buildings in the foreground. The street today is well known as "Antique Row" and features many such shops to browse through and empty your wallet in. Been there, done that !
