Odhner passed away in 1905, his son continued the business, moving it to Sweden during the Russian Revolution. The company passed through more hands, machines were developed further, new models released and were in common use till the early 1970s.
I'd love to take one apart and play with it (probably ruin it) but fortunately there are people online who have done detailed studies of these mechanical miracles.
How to use one here.
History and lots more here.

I'm having a sudden flashback of one of my high school math teachers (70s), who wanted to familiarise us in the use of the Curta calculator.
He had managed to round up a half dozen of them for the purpose, I wonder now with what funds, as they were never cheap, and worth today ten times as much it seems.
It has an interesting history as well.
