An interesting picture, and certainly like nothing you'd see in my part of the world.
I can make out the secondary links between the transformers and connecting to the 240V lines in delta configuration.
Why did the PoCo install two services run with separate 240 delta and 120/240 3-w feeders, rather than just running 4 lines to each building and then tapping off as needed for each meter?
The only reason I can think of is that with the 240 delta likely to be used for motor loads, using separate feeders could minimize the dimming of lights during the starting surges.
What's the significance of the yellow marker bands on the poles?
