Russia 1 r. imperforate bloc of four, used with cds “CHITA” 28 1 20" to reverse of registered envelope to Stockholm, Sweden with red transit “LONDON” and arrival cds “STOCKHOLM 30. 3. 20”, the envelope somehow creased and with wrinkles, still fine, together with Russia 1 r. imperforate horizontal strip of three tied by cds “CHITA 17 11 19” to reverse of envelope to Washigton, USA, with archival holes. A most appealing duo, showing the Kolchak rates in the Transbaikal region both during the Kolchak (November 1919) and the superseding Semenov (January 1920) regimes
