Thanks guys, hope it proves useful. Yep, that 'A' and 'B' thing can occassionally be a bit of a headache, as Peter and I have just found out !
The Luftwaffe part will be along similar lines, but don't expect a really in-depth explanation or breakdown - it's designed to be a basic guide to the main points, and mainly for those who have little knowledge of the structure, and the way the markings systems worked. It'll be a simplified way of finding out what, why and when, for example, paritcularly on some of the changes to, and development of camouflage schemes and the tactical I.D. colours etc.
With a bit of luck, I might have it posted in the next two or three days - if I can stay awake !!
