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.
As this volume is long out print it is likely that you may be hard pressed to locate an unused edition. You may however be able to locate a used copy on the secondary / used market. Happy hunting!
