I love the myriad small freighters of that era, that is a very nice centre island one you just made.
Let me know specific boats you may need photos of and I will be happy to dig for you, i am member on a number of naval history forums and there is a lot out there but it takes digging sometimes. thanks so much for your amazing efforts, this remains I believe potentially the only and best WWI full size naval sim yet, the others are strategic, or too small (Storm Eagles) .... i am praying that you have the strength to complete..and will do what I can to help you out.
This is an excellent site for photos and info on any ship from just about any navy:
