I was able to scan the only known copies of the Army War College's 1940 pre-WWII Garand Plates. There are actually eight plates in all, but this one is one of the most interesting. Beautiful and in color to boot! Go to: http://www.nicolausassociates.com/M1_Garand.htm. Scroll down until you see "Color M1 Garand "Gas Port" Rifle Drawing / Plate".
