Hi Bob - have just found your topic thread and have enjoyed it immensely! I have a book: Farrell, F. A. (1920), The 51st Division War Sketches,
Edinburgh, Jack Ltd and I think you can also access it and the plates on-line (you may already know it and if so I apologise) this is the link http://archive.org/details/51sthighlanddivi00farr
When I saw your work it reminded me of the book which if I remember correctly has about 60 water colour sketches. I did count the pages but that was a while ago. I am not a painter but I do enjoy drawing with pencils and occasionally I use water soluble pencils. I have long had ideas for WW1 projects that I would like to try - this book gave me some ideas and now your work has rekindled my motivation! Thank you for sharing and I will continue to follow your work.
