Kirk, it probably says PNWPSCO, for Pacific Northwest Public Services Company, one of PGE's many company names (1930-32). Apparently it was a holding company, with PGE as its electrical subsidiary. See http://www.iinet.com/~retireeski/history.htm
A detailed history of PGE written by a former PGE manager is available at the Estacada library. It's the only copy I know of, and is the source of the "Clackamas River Basin Development" chapter that's posted on this website. Another source for PGE's corporate history is the book "Electrifying Eden" by Craig Wollner, also available through the library.
Thanks D., I wasn't sure if that second letter on the pole tag was an N or a W. I'm going with N now that you've found that the company name PNPSCO was active during that time frame.
I'll have to check out that book, it sounds interesting.
