Sowerbutt's Fuel

"Jimmy did some big deals after the war." The retired writer for the East London Pioneer, who still has the notebook from his early 1960s interview with Jimmy Sowerbutt, said: "Petrol was scarce with the currency restrictions and ordinary civilians didn't get their allocations back until '48. Jimmy had big cash reserves from the war and invested thousands of pounds in petrol, bought from the GIs. He stored it in tanks on the disused airfields and sold it gradually for a fortune. Made his money back many times over."
