Dspark,
Two upper elements were on one 120V leg, each with its own switch, the lower element was on the other leg. The rotary switches had "HI" "MED" "LO" and "OFF" positions. It ws really a multiwire setup rather than a true 125/250V.
There was a gravity type thermal cut-off safety switch that had to be held into place to turn the unit on, and a thermal coupling to a temp guage with a switch to choose upper or lower probes.
No timer, very lo-tech. (read old)
Other than the obvious problems, it seemed in very good shape.
The conductors were insulated with a waxy paper looking fiber, very easy to strip, but in good condition. The only things in bad shape were the work of various "handymen" through the ages.
