Cornell-dubilier Electronics Division cd-3 capacitance decade box 0-10 microfarads in 1 MFA steps the was a 3 accuracy unit, another model cd-5 attractive red Bakelite case with no cracks or significant blemishes, unsure of vintage, it has metal capacitors inside.
Tested the steps using a Beckman industrial capacitance meter, all values read about 15 high. This capacitance range works for testing most 1930s radios as they usually had low values in their filter networks and used large inductance's combination to get the necessary filtering.
I added the new felt pad feet so bottom screws would not scratch your bench. Then checked for leakage using my 500 volt bench supply, all values showed nearly zero. Buyer pays the return shipping. I am assuming they use an oil dialectic based on the square case sizes removed bottom for inspection.
