One of the objects is very similar to a previously posted photo

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.

Was out driving today and saw some in the real world, of a more modern,
presumably plastic, construction.

Note that the new ones have ratcheting clips instead of having to be
tied on with wire.

Wouldn't be surprised if some of the ceramic ones were still up around
here. If I see one and can get a picture I'll put it up on the same
site.
