In the autumn of 1981, Arkhangelsk, Vologda, Yaroslavl, Ivanovo, Vladimir, Ryazan, Lipetsk, Voronezh, Rostov-on-Don, Krasnodar and regions to the east of those named (about 30 in total) parted ways with Moscow time.However, the convenience of common time with Moscow turned out to be decisive - in 1982, these regions again switched to Moscow time.
Currently we list 45 regions under Europe/Moscow. Is there some way to reliably come up with the list of "about 30" Russian regions that deviated from Moscow in 1981? If so, we can find the largest city in that area and come up with some approximation to a Zone. In the meantime, we can add your remarks to the already-existing commentary saying that this part of our Russian time zone history is incomplete, as per the attached proposed patch.
