By far the best solution availlable:
By Histoire & Collections :
Chars B au combat - Hommes et matériels du 15ème BCC by S. Bonnaud and François Vauvillier . The book is right here with me. May I tell you that you can find inside color plates of any B1 you can imagine ( must have more than 100 profiles ) The majority of the plates is complemented with at least one wartime picture. Also focus on insignia, units, badges, uniforms, operations. Whatever you can imagine this book has.
I found it at Amazon France right here:
http://www.amazon.fr/exec/obidos/ASIN/2913903428/qid%3D1089580019/402-2233511-9132913
Note that the book is in French only. No English translation was made in this volume, perheaps because the subject is french.
Mon Français est, je pense, trén bon. Mon anglais n'est pas la meme chose il'y a beaucoup d'erreures dans mon gramatique saxonique, so if French is understandable for you, go for it, it's a terrific acquisition to your library. If not, personally sometimes I don't care. I have here too many Model Art and AJ Press books and I can't understand a single word of Japanese and Polish. Just bought them for their pictorial content.
