For anyone seeking some a good readable book detailing the career of the Avro Lincoln may I recommend "Lincoln at War", by Mike Garbett and Brian Goulding. Published by Ian Allan 1979 and reprinted 1999. ISBN 0 7110 0847 7. 176 pages. Well illustrated with plenty of B&W photos of both British and Australian and a few of Argentinian and demobbed aircraft.
