Top Hats In Tobruk. Written by Kenneth Rankin who was an officer in 152 battery 51st HAA regiment. My Grandfather served in 153 battery of the 51st hence i get the book. The book is basicaly Rankin's diary from the North Africa campaign. I find people actual words from the time to be fascinating and often more insightful that a history book. If you have an interest in AA or the NA campaign then its worth tracking down a copy.
