Correspondence, manuscripts, notes, photographs, and printed materials concerning the Leĭb-Gvardiĭ Izmaĭlovskiĭ Polk (the Izmaĭlov Regiment of the Imperial Guard), and of its emigre veterans' association, the Soi︠u︡z Izmaĭlovt︠s︡ev (Union of "Izmaĭlovt︠s︡y"). There are materials concerning the War of 1812, the Russo-Turkish War of 1877-78, World War I, the Civil War, and the emigration. Most memoirs by veterans of the regiment cover World War I and the Civil War. There are biographical notes on members of the regiment from its formation in the 1700s into the 20th century, and also photographs and engravings. Printed materials include histories of the regiment, the oldest dating from 1830, and 14 bound volumes of the "Izmaĭlovskai︠a︡ Starina" (1930-40).

The collection consists of correspondence, manuscripts, memoirs, minutes of meetings, documents, maps, photographs, and printed materials, mostly relating to World War I. Correspondence, mostly to Owie, includes a letter from Grand Duke Gavriĭl Konstantinovich. Memoirs are by Sergeĭ Konoplev concerning World War I, and manuscripts appear to be by Owie on the war and anti-Communist topics. Minutes are from the Society of Officers of the 3rd Infantry Regiment of the Life Guard (Leĭb-Gvardiĭ 3-iĭ strelkovyĭ polk). Maps, documents, and photographs deal mostly with Owie's service during World War I. Among the photographs is one of Nicholas II from 1913.
