I keep trying to think of historical achievements for the Mossie, the most obvious one I can come up with is *cough* the Scherf.
Charlie Scherf shot down five enemy aircraft, air-to-air, on a single sortie in a Mmossie FB VI. His Nav on the op was F/O "Red" Stewart. Other pilots got four on a sortie, however Scherf was the only one to get five, and in daylight at that.
I should be able to find a couple for the bomber Mossie, first cookie on a city target, first cookie on Berlin (= HQ?) spring to mind.
