1921z (23 Jan) to Harbin, f.w. Coat of Arms surch 20c in pair, tied by clear strike of Yaomyng Russian PO T&S type 2 cds. Obviously philatelic and probably prepared during the last few days of the office's existence under Russian control. Similar cover of the same correspondence is seen in Dr. Casey's collection.1921.1.23 窑門寄哈爾濱，背貼軍徽圖改值20分雙連，銷窑門俄局T&S 2型日戳。顯然為集郵封，應是該局結束運營前數天製作。Casey集藏中亦見相似信封。
