Hi Henry Martini
the books you mention won't be cheap , the last copy of the ' RD Doctor ' I sold was 130 GBP's which did include postage , the other ' Rorke's Drift By Those Who Were There ' would be a little more , it's basically impossible to find due to the fact there were only 500 or so printed ?? . Nothing online as far as I'm aware . Waters account was published 13th June 1879 in the Cambrian Newspaper , this information from Vol 4 Legacy ; Heroes of RD... by Kris Wheatley , also difficult to find .
