The Royal Navy 1939-45 (Elite 79) by Ian Sumner, artwork by Alix Baker (Botley, Osprey, 2001; ISBN 1841761958)
The uniforms and organisation of the Senior Service during the Second World War, in the characteristic Osprey style.
'As with all Osprey books, well illustrated, good photos and enough information to make you want to know more about the subject. ... Helped me understand what my grandfather went through in the Arctic convoys etc having had no previous knowledge of the so called "Senior Service", being a "Pongo".' Baldrick399 on amazon.co.uk
