One of the objects is very similar to a previously posted photo from a
couple years ago, so I added another picture for a total of seven this week:

Sorry for going all retro, but on #931 from last week or so (the 3-phase
wire hanger), what's with the swirly Art Deco styling? Is it just that
this was designed in the days when Deco was all the thing?

Thanks,

The one longer arm with the smaller notch for a wire is for the
messenger cable. That is a steel cable much stronger than the current
carrying cables. The messenger cable allows the wires to be pulled
tighter and higher than without it or used for longer spans. On three
phase applications they would be used for low voltage only.
