Many thanks chaps. Bruce, as a result of your prompting I have bought myself a copy of Foremans FCWD to replace the one I used to have which was destroyed when the boiler in my attic sprang a leak
. Michel - to my shame I got my information about the massacre of 9./JG2 from Wikipedia and now am embarrassed that I did not see there was no corroboration in any of my other sources.
best regards
Keith
