The Albatros L.57 was

Design and development
After the 1918 Armistice the German aircraft industry was heavily controlled by the [[Allies] and there was a period during which all construction was banned and large numbers of military machines destroyed but by June 1920 20 manufactures had been given clearance to resume some activities. Any production had to be agreed by the Committee of Guaranties and was close scrutiny of each proposed type to ensure it was a true civil aircraft, not a military type in disguise.

Design of the L.57 was started in 1920 and construction of four was under way when the factory was inspected in February 1921; as a result all material was confiscated. One L.57 was required to be delivered to France but it is not known if it ever flew. Despite this, in November Albatros were offering the L.57 to Denmark as a military transport. In May 1922 an Albatros type (unspecified but probably the L.57) had been approved as a civilian. Approval of its bigger successor, the L.58, did not come until June 1923 but despite the gap there is no solid (R&R describe this as an "enigmatic" period is Albatros' history) evidence that an L.57 was completed or flown. (In agreement with the NACA report)

NACA report names the built aircraft L.58 (they describe the L.57 as unbuilt*), 16 m span The dimensions broadly agree with Lailes, though not Flight, even when overhang removed.


 * some illegally built, according to R&R, p.54. R&R has more on the L.57 pp.89-90.

18 m span and two versions with Falcon the L.58a

German Wki: article + useful ref book: like histav, the L.58 and L.58a are compared and spans given as 18 m.

14.17 m was span of L57, which had noticeably lower AR.(Ref 1)
