NB! 1940/1941 set of 3 field post letters from Soviet military navy base in Haapsalu to Moscow
Rare set of 3 letters from Soviet military base in Haapsalu to Moscow. These letters must not be confused with letters from Estonian units incorporated to Red army that use similar triangular unit cachets. Likely total only about 20 letters from Russian bases are recorded. Note this set includes letters from Soviet navy field post station “Leningrad 305” in Haapsalu, not mentioned in literature (300-302 are mentioned, I also have 303). The items from 1940 with single line “KRASNOARMEYSKOYE” (“Red Army letter”) are especially rare.
