After subjecting the map to all sorts of lighting conditions i was able to pull a bit more detail off of my modified forced projection of the map. Thanks to everyone who has helped to point out details i missed.
Check out the first entry of this thread. I just UPDATED the map to include Sea zones and Convoys. Note that Yellow lines on the map and also yellow convoy boxes are those which i could not clearly deceiver. Enjoy.
P.S. Uruguay is back on the map, as my light test clearly indicated its borders and also its blurry illegible name printed on the map. That means that all Mainland south american countries are represented on the map besides Chile. Other small details changed.
