 Curta Calculator - Historic Rally Equipment
Before the dawn of the portable electronic calculator in the early 1970s, all serious rallyists used a Curta in conjunction with a 1/100th reading odometer such as a Halda Twinmaster or Tripmaster.
The Type I, the smaller of the two, has an 8-place setting register, a 6-place indicating dial, and an 11-place answering dial; the corresponding capacities of the Type II are 11, 8, and 15.
The Curta came in a special shock-resistant carrying case, originally made of stamped metal.

 Programmable Calculators: CURTA Type II
In the CURTA, sliding levers are used to set the corresponding drums to the desired digits; when the crank is then turned, the digits are transferred to the accumulator by addition.
The ability to shift the entry mechanism relative to the accumulator is what makes it possible to use the CURTA for multiplication; you can shift the machine to the desired decimal position, perform the necessary number of rotations, then shift to the next position as you multiply with each successive digit.
The CURTA came in two basic models: type I and type II CURTAs are distinguished by the number of digits that the machine can handle.

When the Curta is held or mounted in the proper position (with the factor input slides facing the operator) the time readout section (fl) will be near and facing the operator.
Your Curta will now show official mileage and time in the time readout and your mileage in the mileage readout thus eliminating the necessity of correcting the official mileage to agree with your odometer.
The mileage and time that appear on the Curta before starting to add or subtract time should be noted before the operation is begun to insure when you are finished the mileage is the same as when you started and the proper amount of time is showing on the Curta.
