The Facit Standard is a very well designed mechanical calculator of the pinwheel type. It has a special mechanism to ensure the number wheels don't over-rotate, which allows the wheels to move easily, resulting in a very light action. It also has the counter inside the main body rather than the carriage, a large capacity output register, and a clever tabulation mechanism.
