Nautical Charts as reference
sorry if this thread is redundant, but I'm really bad at searching in forums so I thought I'd just start a new thread on the topic after a short, seemingly fruitless search.
I'm looking for historical nautical charts as reference material, preferably late 17th, early 18th century. I had a look at The National Maritime Museum link, but I couldn't find anything usable. Might have just been my own stupidity.
Does anyone know a good source for those? The David Rumsey Map Collection seems to have some, but I was hoping for something more specifically nautic.
