As to the Ju90, I know that the combat reports mention attacking them but my wife has hidden my Aircraft of the Third Reich by William Green which I know had some info. As I am sure you know there were only about 11 or so built, all prototypes. The first 4 seem to have had the wing of the Ju89 and the first 2 crashed quite soon. From V5 onwards some if not all had a revised wing much less swept and akin to that of the Ju290. The horizontal and vertical tails were also changed and at some point the windows changed from rectangular to round or vice versa. The last few "B" types were converted to 290 prototypes and although I know some served in Norway I can find no mention of Iraq! Perhaps this is a question best aimed at Fran and Knegel.
With increasing age should come wisdom and tolerance, but as the saying goes, "there is no fool like an old fool" as I prove regularly!
