Not really, i've managed to get hold of several books about 'J' and Phantom which have shed a bit more light on their operations. As i may have mentioned here (or on another thread) i need to research the nominal roll of the British air mission in Belgium at the outbreak of the war as i firmly believe that my relative served with them - but that's another story ! What's your interest in J service ? I may be able to do a look up for you. Mac.
