I have asked Agis over on his thread if he could possibly post some pictures of different sized ships. In the back of my mind I knew there was a site with something comparable and now I have remembered. It is for HMS Hood - follow the link and take a look at the column on the right. I would have put the pictures directly here, but maybe the people from the H.M.S Hood Association might get a little agitated. It does not have every manufacturer, but it’s a start.
