CRIMEA
From a Crimean collector I received a list from 1937: 273 post office in Crimea. So there is still a lot to collect.
SOVIET UNION : FURTHER POSTMARKS
MIROLYUBOVKA / KENDZHE
Below you will see a settlement form from the Soviet era. These forms were used to settle amounts between different offices.
The postmark is from КЕНДЖЕ КРИМ АССР [KENDZHE KRIM ASSR], 2-11-1940.
To locate this place I needed the Russian Wikipedia (lit. 1): in 1945 the name was changed to МИРОЛЮБОВКА [MIROLYUBOVKA]. It is a small village with 771 inhabitants (2014). The old name is a Crimean Tatar designation. The name is mentioned for the first time in 1784. After the annexation of Crimea by Russia on April 19, 1783, the village was part of the Perekop district.
According to a document dated October 21, 1805, in the village of Kendje there were 16 courtyards and 98 inhabitants, Crimean Tatars.

The Russian Wikipedia (and Google translate):

The village of Kendje/Kendzhe was abandoned by its inhabitants in 1860-1864, due to the emigration of the Crimean Tatars to Turkey, a side effect of the Crimean War of 1853-1866.
The village will receive new residents. According to the List of settlements of the Crimean ASSR according to the All-Union Census on December 17, 1926, in the village of Kendzhe, the center of the Kendzhensky village council of the Dzhankoy district, there were 32 courtyards, of which 30 were peasants, the population consisted of 142 people. At the national level, 107 Russians, 34 Ukrainians and 1 Latvian were taken into account. According to the 1939 Union-wide census, 345 people lived in the village.
By the decision of the Presidium of the Supreme Soviet of the RSFSR of August 21, 1945, Kendje was renamed Mirolyubovka.
Here is another form with the same postmark.
