Despite the date being shown as 1943, I think this is a newsreel film released much later, using a compilation of film footage, a common occurence at the time, due to censorship.
I've seen much of tis footage in a film describing the return of this French Squadron to France, some time after "D-Day", with the closing scenes showing the Bostons landing on a French airfield, taxiing in, and the crews celebrating as they disembark.
I therefore believe that the stripes on the camera ship wing are painted-over AEAF stripes.
