This is a fully complete and working Original-Odhner mechanical calculator, developed in the Soviet Union during the mid-20th century. With all original panels, dials, and crank intact, it’s a fantastic example of Soviet-era technology and mechanical precision.

All functions operate as they should, and the unit retains its front casing, giving it a much more finished and display-ready appearance than similar exposed models.

📜 Background:

The Odhner calculator was invented in Russia in the 1870s by Willgodt Theophil Odhner, a Swedish engineer working in St. Petersburg. He developed the pinwheel mechanism that would define mechanical calculators for decades. Early production began in Russia under his supervision.

After the Russian Revolution, the original Russian Odhner factory was nationalized by the Soviet state and continued production under state control. Simultaneously, Odhner’s family and business partners moved manufacturing to Sweden, where production continued in Gothenburg (Göteborg) under the “Original-Odhner” name.

As a result, two lines of Odhner calculators existed:

• Soviet-made models (often used in state offices and institutions),

• and Swedish-made units, known for their build quality and design consistency.

Both versions are now prized by collectors and historians for their role in the pre-digital computing revolution.
