recently ı watched the 633 Squadron on TV . Know it is fiction , accept the book is better as the movie version is somewhat sanitized and the visual effects are unconvincing for us the born in the 70s generation . Anyhow the planes surprised me in that many of them had flat bomb aiming panels in the nose ; the noses were painted to resemble the planes to Mk.VIs but as ı said the flat panels were unmistakeable . Doubtless they were late model reconnaissance types that had survived up to that day , while an Air International article of 1984 wellcomes the solitary flying Mosquito of the period ( a trainer version that played in the movie and sponsored by the RR , no less ) had finally given up the untruthful markings of HT _ E . What makes me specially wonder is that the visual effect showing gun firing by the Mosquitos has a clear unpainted panel . The relation of this to SPF is , were there any attempts to fit guns to versions with glass noses ? ı have both Airfix and Matchbox 1/72 models ,still in their boxes and the instructions for the latter show that Mk IX had 20 mm guns which ı find unconvincing . But maybe there were intruder versions .
