Britain Had No Phosphor Bronze in 1943 — So Vickers Cast Bearing Shells From Melted Church Bells"

March 1943. Britain's phosphor bronze supply vanished overnight. Every Spitfire, every Lancaster bomber, every tank—all ran on precision bearings that required this metal. Engineers had 11 days before the entire war machine ground to a halt. The solution was as desperate as it was brilliant: melt down church bells from bombed cathedrals and transform centuries-old bronze into aircraft engine bearings. Bells that had rung for 300 years became the metal that kept Britain's fighters in the sky. This is the untold story of Dr. Elizabeth Mortimer's metallurgical breakthrough, the foundryman who suggested the impossible, and how bells cast in the 1600s spun at 3,000 RPM inside Merlin engines over occupied Europe. Some of those bearings are still spinning today in museum Spitfires. The bells never came home. #WW2 #BritishHistory #UntoldHistory #WorldWar2 #MilitaryHistory #Engineering #Spitfire #ChurchBells #WarHistory #WWII #BritishEngineering #HomeFont
