Yes they were the calculators of the past. A few people still use them today.
Mechanical calculators could perform basic arithmetic functions such as addition, subtraction, multiplication, and division. They could also perform more complex calculations such as square roots and logarithms depending on the model and design. Mechanical calculators were used before electronic calculators became prevalent.

Enigma was way before computers, it was done by hand and crude mechanical calculators.
Manual calculating devices are tools used for performing arithmetic calculations without the aid of electronic components. Examples include the abacus, slide rule, and mechanical calculators. These devices rely on physical manipulation or mechanical parts to facilitate mathematical operations. They have largely been replaced by electronic calculators and computers but are still valued for educational purposes and understanding mathematical concepts.
A mechanical counting machine is a device used to count items or currency accurately and efficiently. It typically consists of rotating gears, levers, and dials that increment with each item counted. These machines were commonly used before the advent of electronic calculators and are still used in some settings for tasks like tallying votes or counting money.
