The 40mm Bofors anti-aircraft gun is one of the most successful designs of all time. It was first produced in 1932 and a heavily modernised version is still being manufactured today. Used by many nations, the British first started testing examples in 1937 and it quickly became the army’s standard light AA weapon and by 1942 5,025 were being produced a year. The weapon also saw extensive service with the Royal Navy on board ships as an effective defence against aircraft and light craft. The bofors used a clip of four rounds of fixed ammunition that was fed manually into the top of the gun:Tonight we are looking at the casing from one of these rounds. This a tall and slender case, made of drawn brass:A large groove at the base engages with the loading clips and is used as part of the feed mechanism of the gun:The base of the casing is heavily marked with various marks, dates and proofs:These all have their own meanings:Cyril Perkins commanded a bofors gun detachment on the coast of England:
Those aircraft recognition charts crowded into my mind as the silhouettes of ME 109’s momentarily filled my binocular lenses. ‘Engage’ I screamed and back came the response ‘On’ and again ‘On’ as the two aircraft now with swastikas clearly visible came within range but no order to ‘Fire’ came from Bob and I looked across to determine Why ?
The Bofors Gun was depressed below zero degrees and could not be fired until the elevation moved above zero plus five and we waited as precious seconds ticked by.
Some four hundred yards from shore the two planes separated and zoomed upwards to make a circular attack on Sandown and in that instant the elevation moved above zero plus five and Bob yelled ‘Fire’. But it was too late as our tracers screamed skywards our target banked and swung away out of range. We watched and waited helplessly as the two planes swooped on Sandown and dropped the bombs they carried under each wing. Then they were over us again and our tracers joined with others as we concentrated on the plane seawards of us.
I heard the chatter of our quadruple Lewis Guns as Tommy and Toddy blazed away at the second plane as it crossed our dead arc and then it happened. Tracers and aeroplane merged into a huge crimson flame and our target literally disintegrated before our eyes. As we stopped firing bits of aircraft floated seawards dropping into the sea below causing hardly a ripple on the water then disappearing as the ever hungry waves devoured them. I scanned for another target but the one that got away was already a fading dot above the ocean a survivor perhaps to placate a German mother who would mourn the loss of a son that day.
