Very messed up 3way switch! Help please

My son just bought a 105 year old house. Lots of things wrong with it.

A switched outlet reads an open neutral when the switch is off, but normal when the switch is on. It shouldn't read anything when the switch is off.

I opened it up and found it was a three way switch. With the switch off, I found voltages of 67 and 73 volts on each traveler. With the switch on I get 120v and 0v.
I searched and couldn't find anything else on this switch; there are things all over the house on the circuit, but nothing on the switched circuit. I did find the other switch and that works properly; though I didn't check voltages on it.

I am familiar with phantom voltages, and these are real.

All I can think is that there is load on the travelers, but I sure can't find it.
Any advice would be appreciated.

In older homes it was fairly common for them to switch the neutral instead of the hot, which sounds like what you have there. Use caution when working on that circuit.
