The collection consists of correspondence, a diary, manuscripts, memoirs, notes, a subject file, photographs and printed materials. Correspondence is primarilly addressed to Orlov and his wife. Manuscripts and memoirs, chiefly by Orlov, deal with Civil War topics. Orlov's diary covers the years 1918-1921. Notes are on World War II, and the subject file concerns the death of Orlov. Photographs include a group picture of a Gallipoli Society meeting in Prague. Printed materials include clippings, mimeographed materials, pamphlets and copies of periodicals, all relating to the Gallipoli Society.

Manuscript and typescript memoirs (in all 600 p.) that deal chiefly with Kamenskiĭ's military education, the imperial court, his service during World War I, his service as General Petr Wrangel's diplomatic courier in 1921-24, and the emigration in France. Part of the manuscripts on World War I consists of copies of his diary. Some hand-drawn maps, photographs, and six copies of the bulletin of the organization of veterans of the Jaeger Regiment complete the collection.
