Nice, although the aircraft in post #20 is a PB4Y-1 Liberator. Note the absense of a vertical fin and also the turbo-supercharged engines, which the PB4Y-2 Privateer did not have. See the pictures in post #7 for the Privateer's engine nacelles.
Lots going on on the nose section. Just looked up "Umbriago"; a song by Jimmy Durante. Also Italian-American slang for "being drunk as a skunk" Many aircraft carried "Umbriago" as nose art
