And back in my TA days (late 70s), if you referred to anything by its "L-number" then you were labelled a "train-spotter" or "sad anorak", as one NCO said when putting me strait after doing so one time as a fluffy newbie "L-numbers are only for shiny-ar*ed stores clerks for ticking off stuff on their forms. We squaddies call that thing an SLR, and
never an L-whatsit."
