I understand the British markings (the Broad arrow in particular), and I understand the Englandicon marking generally meant it went to America, but what makes you say Australiaicon? What I was getting from that thread was that the 'P' with a heart around it meant a parallel bore, which was a rifling test by the UK to see what type of rifling preformed the best. Is it possibly another marking saying that, or was I misreading that information?
