This Odhner's Arithmometer was made in 1906 in St. Petersburg. It is a very basic pinwheel machine, with no safety mechanisms at all. This is a type Ag, which means it has a 9x8x13 capacity with an overflow bell. It was a bit of a struggle to do a division, but it would have been easier if it were still mounted onto the original heavy wooden base.
