This one supports electric light and trolley communication wires and is the third pole in on the right of the overview image I just posted: [id=594078102].

As you can see, the electric lighting service lines are supported by CD 162s and a couple CD 149s. On the same crossarm is an iron break-arm bracket which likely was used to split the circuit for a series street light (not in the photo). Of interest, we also see what appear to be a couple CD 145 beehives tied to DC trolley cable lines.

Along with this image are a few more, they are close views of poletops in the overall scene. Individually click "Previous" to see each of them.
