comparative display of standard counters and later IBM ASCC-Mark I counters
This display consists of two parts--a smaller part (the new Mark I style) and a larger part (the old "Standard Pair")-- mounted on a nickel rectangular base.
The larger part consists of a metal plate with several gears, coils, and movable metal arms connecting the various parts. At the back end of the plate are many wires attached to an upright, black frame of insulating material.
The smaller part is more compact, consisting of two metal plates, each with two small coils attached, and an orange piece with a hole cut out for a dial. The numbers "0 5 1 6 2 7 3 8 4 9" are printed on the orange piece around the dial. At the back of the smaller part is a black plate with many wires looping through it. The wires are wrapped in a bundle further back.
