. . "The Ordnance QF 75 mm, abbreviated to OQF 75 mm, was a British tank-gun of the Second World War. It was obtained by boring out the Ordnance QF 6 pounder (\"6 pdr\") 57-mm anti-tank gun to 75-mm, to give better performance against infantry targets in a similar fashion to the 75 mm gun fitted to the American Sherman tank. The QF came from \"quick-firing\". The gun was also sometimes known as ROQF from Royal Ordnance (the manufacturer) Quick-Firing."@en . . . "Ordnance QF 75 mm"@en . .
