Never had heard of the Curta...spent about hour reading
about this machine...one I read how people who tried to
disassemble sending the parts back to the factory to be
be put back together.Amazing machining involved
The cheapest I saw on ebay was $900
Pretty heavy I imagine
I have a Curta II model. They are the smallest four function calculator ever made. They weigh mere ounces and are built like a Swiss watch. Their nearest competitors, such as Ohdner or Facit, weighed 10+ pounds. The controls are smooth as silk. When I turn the crank, I feel and hear the faint sound of gears whizzing at high speed. As I said, they perform four functions, but division is tedious.
