Dominica - King Edward VII and King George V watermarks

I am working on a set of posts studying the stamps from 1903 until 1938 for our Facebook Group - British Colonies Stamp Collectors. As a starting point I created a chart showing the watermarks as well as the alignment of the various sideways watermarks used for these stamps. They are described in the Stanley Gibbons Catalogue, but I think this visual chart will be helpful to anyone who is working with these stamps. Please feel free to double-click the image and save it to your PC is you think it will be helpful. You can then use a Photo Viewer application to expand the image to see things in more detail.
