Royal Navy Camouflage Vol. 1-4 by Alan Raven
Alot of these books are long out of print, some are quite expensive in the collector's world from what I've heard...I just saw Volume 1 of the Luftwaffe Aircraft Painter's Guide go for $250 on Hyperscale...sheesh, I have all 3 volumes...maybe I should cash out, huh? I know the Raven and Roberts boos are now worth a mint...
