While in Tarawa Stan made a credible fake sub machine gun using a Holden exhaust pipe and other bits. It was a bit too long to fit in his suitcase so he carried it wrapped in a hesian covering aboard an Air Nauru flight into Melbourne. (This was in the 1980's). Customs was on to him when asked if he had anything to declare.
He unwrapped the fake gun and showed it to the sceptical Customs chap who examined the replica gun (it was very realistic) and went to confiscate it saying "You could kill someone with this."
Stan arced up and said semi-jokingly that "the only person it would kill is you unless you let me have it back."
I can vouch for the authenticity of that story, because after that clash with Customs he was given the fake gun back and he came back to our house and told me the story.
