6304' was one of the very early Ju52s in Portugal. It seems to be serial no. 5661, which came to Portugal in 1937 as '104' and later '204' and '6304'. The aircraft was withdrawn from use in January 1968 and was later moved to playground at Coimbra. In 1994 the aircraft was sent to Norway for restoration at the Norwegian Aviation Museum. In 2000 the aircraft returned to Portugal and is now prepared for display at the Museu do Ar at Alverca in Portuguese livery.
