Attic and basement are real good ideas. Your new toy should be a big help.

If you get stuck, another method of attack is check continuity between
possible ends of wires to see what the actual wiring is. Include the
light sockets. (I would also verify the socket screwshell connects to
the neutral.) When measuring continuity you have to watch there is not
voltage between the wires. If you don't have a good understanding of
3-way and 4-way switches (one of the switches was 4-way?) this method
may not help. If you work out what the wiring is you can determine which
wire should be the hot feed and trace it. K&T wiring problems can be a
PITA.

I will be heading for the attic in a day or two, especially now that I have
the tester.

Both 3-ways have only 3 wires and it doesn't look like any wiring was
removed from either one. It all looks like the dusty old original wiring,
and the switches I took out and replaced look like they were the original
switches -- ancient.

That sounds right. If you can see the wiring from the attic or
basement would be the next place to go for clues.

Trying to re feed the switch from another circuit sounds like the only
way to continue.

Do each 3-ways have only 3 wires? Does it look like wiring has been
removed from any of the boxes?
