My first thoughts were DeWilde and Buckingham, but they don't have the proper number of letters. The only one I can think of that DOES have 8 letters is "Richards", from Westley Richards, the patentee of the Richards All-Range bullet. Have you got any of the letters that cross filled in?
Oops. And yes, if you include artillery, Mk 7 has already mentioned "Shrapnel".
