A book dealing with Russian Postage Rates before 1967 (Russian Postage Rates, by Allan OLIVER) exists. It is, however, reputable; restricted use. We have tried to negotiate the rights, without success. As this document is now available on several open-access websites, we are now making it available to you here.
Various websites also deal with postal rates:
the site Phila-Ouest which offers, via its "Tarifs postaux" button, a French rate calculator from 1849 to the present day.
