В.Шавров История конструкций самолетов в СССР до 1938 г.

"Лебедь-XXIV" ("Лебедь-24")-биплан "германского типа" с двигателями "Фиат" в 230 л. с. или же "Испано" в 200 л. с. О нем в 1917 г. шли переговоры и был даже выдан заказ на 200 экземпляров под названием "Лебедь-24" типа "Альбатрос". Заказ выполнен не был, так как "союзники" во второй половине 1917 г. прекратили поставку в Россию этих двигателей.

Subsequent efforts by Lebedev produced two more types, incorporating the XIIbis modifications but reverting to the Salmson engine. These were the Lebed XIII and XXIV, some examples of which were fitted with floats and issued to the Imperial Navy. Altogether, some 250 aircraft of the Lebed XII and variant types were produced, and it is perhaps significant that 171 repair kits were provided by the factory!
