I have been reticent about acquiring knowledge of the ( I once thought boring ) Sherman until very I recently.
From the early 1970s until last month, my only general resource was the 1970s era:
"British and American Tanks of World War II
by Peter Chamberlain and Chris Ellis"
.
Half Price Books has been selling:
"Images of War
Sherman Tank
Rare Photographs From Wartime Archives"
By Gavin Birch
ISBN 1-84415-187-5
priced at $9.99 ( I purchased at discount using a 30 pct off coupon).
.
I view it as a general introductory book for guys like me who have very little knowledge of the tank.
Mostly photos, of course, but the clincher for me was the photo of a heavily camouflaged Sherman in action ( image IWM EA 36533 ) that rivals anything the Germans might have fielded.... as well as
..a general photo study of different types produced
..a list of US Department of the Army Tech manual numbers and Supply Catalogs
...production types, acceptance figures
..British Army Wartime Designations
while the photographs in the book provide excellent diorama inspiration.
.
Thanks to that book, Sherman tanks are now anything but boring for me.
