This is a Replacement Resistor Decade for ESI Electro Scientific DB62, DB52, etc Resistor Decade Box. It is 100 Ω/step, and has been tested to be within 0.01% accuracy (minus the zero residual resistance)....
▲Five to seven dials provide precise and range rich resistances. step (Ω): 0.01. ▲Reference power: 0.05W. ▲Max value (Ω): 0.01~11111.11....

Here is a VERY clean black bakelite WELCH Scientific Decade Resistance box. I have no idea if this works. The knobs turn and the numbers turn with the knobs. The wire screws tie down tight. VOTE TO CHANGE THINGS!...
