Here are two decade resistance boxes (referred to as Ohmic Standards), from Vishay Resistor Products.
Having become used to chunky Cropico switches, I was rather suspicious of the thumbwheel offerings on these instruments. They are better than I had expected but still not in Cropico's league!
Both resistance boxes have steps from zero to 99999 ohm in 1 ohm steps. The larger one also incorporates a calibrated variable resistor (0 to 1.1 ohm).
