This is a scan of an 8 x 10 print that I got from Rick Soller at the Crestwood swap meet in 2007. At this point, my memory of the attribution is hazy. Someone loaned Rick a picture which he scanned and printed at the College. Next time I see Rick, I'll try to remember :) to refresh my memory of the details. I'll also try to locate the original scan; maybe it will show more detail.
Anyway, I count 33 crossarms. The lower ones, at least, seem to have five insulators on each side. I can't tell about the top few crossarms, because the contrast is too poor. If the loading is consistent, that would be a total of 330 insulators. At the right edge you can see about half of a pole which has 14 crossarms.
It looks like the pole is quite close to the store in the background. Notice how the pole is behind the sign mounted on the overhang above the first floor of the store. That pole must be right in the sidewalk. So, even with the very apparent perspective, the pole towers above the five story store's roof. Maybe there was a telegraph office up there?
The JPG compression washes out a lot of detail. If you wish to see the original scan, see: http://picasaweb.google.com/fsmccollum/33ArmPole.
