Took my C exam at RAF Bishops Court in norn iron in the early 70's. Flew down from Aldergrove in the mighty Wessex and reported to the examining officer who insisted I remove the 9mm Browning (loaded) from my waist band holster. He was rather startled when I then removed my flak-jacket to reveal my personal Colt .38 auto (loaded) in a concealed shoulder holster.
The memory of the look on his face still makes me chuckle.
Swing the lamp!
