Not really a comment - just a question. Looking at Drum 1945 pic shows a 5 ? (Could be a 3) mounted on the aft main deck other pics show a twin 20mm on the cigarette deck aft and a 40mm below the bridge fwd all 3 classified as cannon. I presume the .50 cal mg are in presure drums and mounted as needed. Where (and What) is the 2x0.3 cal mg weapon. or am I wrong in my looks at the pics & stats ??? Thanks
