And, where did the well-trained Bryant get his military-style weapons? In an interview with the {Herald Sun} on June 23, 1996, Victorian farmer and gun collector Bill Drysdale said that he had turned his Colt AR 15 in to the Victorian police in February 1993, but he was virtually certain that the AR 15 Bryant used was his, both because of the rarity of that weapon in Australia at the time, and because of the unique mark a gunsmith had made on the barrel of his rifle, which matched that on Bryant's rifle.
The serial numbers were almost identical, and "my rifle also had a collapsible stock and a Colt sight, just as the massacre weapon has," said Drysdale.
The {Herald Sun} noted, "One of Australia's largest firearms importers told the {Sunday Herald Sun} that firearms matching the Port Arthur weapon were as scarce as hen's teeth,' and that the chances of two weapons of the same type, with almost-matching serial numbers, being imported into Australia, were next to nothing.'|" After an interview with police, Drysdale was ordered by them not to talk to reporters any further.
