Is that gorgeous Port Natal, Harbor (1911) map available online somewhere?
I added a link to a higher resolution PNG file of the entire map just below the original map on this page. The scan is from the book which is available at the Internet Archive (https://archive.org/details/natalprovincedes00tatl).
I had a feeling you were a fellow archive.org dweller. :) Thank you!
