Back in the day (early 1980s) the Orderly Officer's pile of useful bumf included a pad of UFO forms in case a member of the public phoned in. They must have disappeared soon afterwards as I don't recall seeing them on anything other than my first tour.
It was an odd collection of stuff in the briefcase and the safe, everything from gloves and the key to rescue the Royal Standard in the event of a fire and sealed envelopes containing instructions in case a royal shuffled of their mortal coil, right through to the UFO forms. Most of it, other than the pad of signal forms, was pretty much useless in dealing with most crises that arose during your shift. I always wondered how the porn stash was maintained though, as it was never the same and sometimes never there.
