Ah, yes, the actual landyard itself........ When we carried them we used to loop a longer home-made landyard around our waists, through the loop and into the holster.
One of the Pom train guards on the night sleeper from the North to Singapore had his revolver stolen by a passenger on the train who, so said, walked past him, nudging him as he went and sliced the landyard. Then got off the train at Segamat. It was loaded too. Needless to say the proverbial hit the fan and thereafter, they were chained with a closed loop sort of toilet chain, looped, you stood in the loop, pulled it up to your waist, took up the slack, made sure that there was enough slack to aim and fire then holster the pistol.
Good times........ Nope, crap!
