Liking the Airacobra! Is the bottom one a Marauder?
 
the 4x 20mm + 4x .303s on the mossie was better, having all the guns in the nose makes for a much better "cone of death" in that you can set the guns to converge at 2000 yards and they will be on an airplane sized target all the way from 0 to beyond maximum range. if the guns are in the wings they are spread out, so if they converge far away, only half will hit up close and if they converge too close they will not hit far away because they will have spread too far

IIRC most guns were set to converge at 200-400 yards no matter where on the plane they were located, some pilots/crew set it closer some further depending on fighting/attacking style
 

It would be interesting to find how these photos were staged.
Night shots to see the muzzle flash with long shutters peed yet crisp enough on focus that shows no movement( speed) of aircraft.
Not every round would be a tracer and all the guns would not fire at the exact same moment.
Flood side lighting on the P39 from above and bottom and back silhouette lighting on the Havoc.

Figure they were parked on the tarmac at night and landing gear and doors were masked in the darkroom.
Or Muzzle flash and tracers were all special darkroom effects.
Pre-Photoshop.

no, often on wing mounted guns each pair of guns was set to converge at a different range, the inner most converging closest and the outermost converging farthest, but even early war MG only planes tended to go to 300 yards at minimum. nose mounted guns like the mossie or p-38 would often be set to converge at infinity (all guns parallel)
 
BRITISH ARMY OPERATIONS AGAINST THE MAU MAU IN KENYA 1952 - 1956

Interesting photo, never seen this one before, looks like these Brits are just getting their L1a1, or SLR rifle into the system, or they have a choice, of packing the No.5 or a SLR..its of interest that Canada was the first country to start mass producing our FN C1 rifle, before the Brits adopted their version of the FN rifle
