Beyond the deams of avarice
When I joined as an apprentice (Trenchard brat) in 1956 I was paid £!.00 per week. this went up rapidly (The biggest proportional pay rise I ever received) to 31/6 a week, most of which was held back as "credits" paid in big white fivers when I went on leave. I discovered many new and interesting ways of throwing up in posh cocktail bars on my first Christmas leave.
