Mechanical calculator by Ohdner

Mechanical calculator by Ohdner (Sweden)
Circa 1940

Nice marchant mechanical, hand-operated calculator.
It's a pinwheel-type machine that can add, subtract, multiply, and divide at the turn of a crank. (Well, many turns to multiply or divide.)

The calculator is in perfect working order.

The carriage, 0 resets etc. are fluid.
There are a few signs of use and one bakelite handle is missing, but the overall condition is very good (!).
