This was not long before the revolution. It's amazing to think that in about 50 years they went from pre industrial in most places to an international, space faring superpower.
Most of Russia is industrial, and a few major cities are post industrial, there are rural regions dirt poor. But Russia has garnered the largest nuclear arsenal in the world with hyper militarizing their society and economy.
Depends on how you define places, of course the empty uninhabitable siberian wilderness is pre-industrial. But perhaps you might want to take into account that Canada and Alaska are also mostly pre-industrial by those standards.
