Danny, I find it hard to understand that officer pay rate chart. I couldn't see a date stamp anywhere but it looks pre-war. Like you, I remember my Sgt and F/Sgt salaries gave me approx 5 pounds 18 a week as Sgt and 7 punds plus as a F/Sgt. (Sorry I don't have sterling abbreviations on my Aussie Mac). It isn't feasible that the commissioned ranks would take a pay cut on promotion.
