Just a note - Tarnopol map is not "Russian" map. The area there is part of todays Ukraine and was never part of Russian (Moscovian) state since its begining as duchy of Moscow. It was either part of Austro-Hungary (before the WAR), Austria, Polish, Lithuanian or Polish-Lithuanian states, independent Ukraine or, if we dig very deep, Ruthenian duchies that predated Russia. The only time it was ruled from Moscow or Petersburg was after WW2 when it was part of Soviet Union, as part of Ukrainian (not Russian) SSR.
