Interesting uses on the DC. This one was definatley 120V AC though. It was still wired to the panel with BX, still tested 120 just before I took it out.
Incidentally since my first post I have found under the house: a soda bottle from the 1920's, parts of a newspaper from 1928, a label from a box of nails stating the manufacture date in 1902, a very old roll of friction tape, a metal lid from an old Mentholatum tin and two cat skeletons.

The Mentholatum lid was right by the friction tape, I wondered if the electrician that was there many years before me used the tin for screws or something, just like many of us do today with small tins and prescription containers.
