The "3822" was a small book that all cadets had serving as a record of their  career in the Air Cadets.  Many 3822 were lost or left in pockets and went through washing machines! Sadly, 3822s are no longer issued to cadets - it is all online through "Cadet Portal".

Below are the pages from the 3822 of Richard Vass - starting in 1963.  It's amazing to see a 3822 in such great condition. Thank you to Mr Vass for sharing that with us.
