Very nice! Looks like everything on it is original too!

Definitely built when the construction standards were moving from 4160V towards 12.5 and 13.8kV... those wood / porcelain guy strain assemblies are another thing apparently unique to NSP but didn't last as long as the secondary racks.

This pole likely bit the dust-swung by the area today for some quick errands only to find the source step-down removed and the line brought up to 13.8kV.

Yeah, Xcel REALLY has it in for 4160V in its bigger towns.
