I am doing a project on Captured Enemy Weapons WWII, and how they where used against their former owners. The story of HMS/M Graph is of particular interest, all that I know is from the Observer's Directory of Royal Naval Submarines 1901 - 1982. Any old salts out there with tales to tell of her service with the RN would be much appreciated. Also I do not seem to be able to find any record of a ships badge for said craft. Congrats on an excellent site. <<< Roister2>>>.
