The Mk.31 was Australian built version of the Lincoln modified for reconnaissance and later maritime patrol by fitting a longer nose. There were 20 aircraft so configured, half of which were used in the maritime role with 10 Sqn from 1953. These were contemporaries of 11 Sqn's Lockheed P-2Es. Airframe problems forced the retirement of the Lincolns ahead of 10 Sqn receiving P-2H Neptunes. A73-62 was sold for scrap in 1962. Photo from: Library and Archives NT

A73-62 was the first new Lincoln delivered with an extended nose to provide room for additional crew and equipment needed for maritime reconnaissance operations. The final 12 Australian-built Lincolns (of 73) were modified before delivery and eight others were returned by the RAAF to Government Aircraft Factory for conversion, including the prototype. -62 was withdrawn from use in 1961. The location of the photo is believed to the GAF factory at Fisherman's Bend in inner-city Melbourne. The airstrip closed in 1957. This is an official photo by GAF.
