<<How much did an ambitious lad working his first full-time job at age 18 or so in 1962 make?>>>

In 1962 I was 17 and a year into a 5 year apprenticeship at at R/Royce, Bentley and Jaguar main dealer.
£3 10s 0d a week including Sat morning overtime.
I ran my Bantam to and from work on a mix of customers' petrol and Castrolite 'left over' after oil changes. Had to clear a whiskered sparkling plug most days.
