Re-attaching Ancient Lamp Fixture


This is a relic two-wire fixture less a ground (unattached to house ground in box). Likely an idiot question. Jackets look woven.

Does it matter which goes back to hot and which to neutral?
Don't they both just complete the circuit?

I realize newer retrofit fixtures identify hot to brass and neutral to silver but the wires on fixture side look identical. Unless there is some other way to identify hot and neutral on aged fixtures?

Will look on the job today but I don't believe the lower socket to be visible. Aren't both connected to the socket?

Look closely at the socket. wire to socket's nub at bottom vs. barrel threads. The wire that leads to the nub should be hot, so I've heard.

Or take it to shop that rewires lamps and they'll advise you.

Or check each wire for continuity to the barrel threads. You have a tester?

Took it to the electrical shop today, they verified copper/hot goes to the nipple and silver on the thread. That was one fixture [pictured]. For the second I'm looking for my tester... have only a basic voltage tester right now.
