ULTRA HIGH VELOCITY GUNS. Further to Rm {William Robotham - Chief Engineer} /RH. {R. Hollingworth} 2/17.11.40. General MacNaughton has now decided to use a Bofor since this has the inherent advantage of being able to accomodate a larger volume of propellant and, at the same time, a more robust barrel than the Rolls Royce 40 mm. gun.
