I recommend http://www.ridgenet.net/~jslayton/Fu...ol4/index.html (and the newer http://www.cartographersguild.com/sh...ew-Found-Lands has a PDF near the bottom of the first page) combined with http://www.ridgenet.net/~jslayton/Fu...ol5/index.html to get some lakes and river markings. If those aren't helping, I could probably do a few more examples, especially if you show the kind of source material that you're working from.
