Also shown in the Avro book is a photograph of T-102 of the Argentine Air Force. The photograph was taken on 24 May 1960. The aircraft appears to be airworthy/operational.
Moot point whether this was a Lancastrian. Another Lancastrian, RAF TX289, new 1946, was sold in 1947 to Argentinian airline of the times FAMA (who also bought Shorts flying boats at the same time), they ran it for a year, then sold it to the Air Force, who used it for a couple of years as their T-65 (T=Transport) until 1950 when it was withdrawn with corrosion. It then seems to have sat around until 1958 when the "Lancastrian mods" were taken off it (presumably they weren't the corroded parts) and applied to Argentinian Air Force Lancaster B-045 (B=Bomber) which was ex-RAF Lanc RA378 sold in 1949. It was renumbered T-102, and crashed on 11 December 1960 with 31 fatalities. Seems a lot of fatalities for a Lancastrian lost en route, unless there were some on the ground.
