I have never seen this version, and I was hoping to be 100% sure on this image. Any help is greatly appreciated.
I see knobs but no tubes

so this is cloth sheathed ungrounded wiring? I have never seen this before, it was odd and this was a 1940 house
Looks like old lamp wire. Did you trace it to its origin? Is it plugged in somewhere?

That makes since, I could not figure out what that twisted wiring would have been. I could not find an end as there was a ton of insulation. I do see knob and tube still in use from time to time just never seen this clever way to use the knobs. Thank you for the help!
agreed, feel dumb for asking this one
I am more concerned about getting things right than asking a dumb question. And no, that won’t be grounded in my opinion.

I would call that knob and tube wiring. The tubes would be present where the wire passed through a hole in the wood.

Looks like modified knob & tube wiring to me, or mayby they thought that just one light in the attic wouldn’t allow the wire to get too hot, so they twisted it to make the run easier.

thank you, this configuration was a new one for me.
This is typical for 1940’s branch circuit wiring. I call it old, unsheathed, ungrounded wiring. Look closely at the condition of the wire insulation, especially at stress areas near the ceramic holders. Often there are cracks. Although not a code requirement, I always recommend upgrading this wiring. The wires and the electrical system are over 80 years old, potentially an insurability issue.

1940’s house I grew up in had this wiring in the attic and garage. It may have been inside the wall too but only the garage and attic were exposed.
