Nature and nature's laws lay hid in night;
God said "Let Newton be!" and all was light.
Nice bayonet, seems to have been a lot of enfeild bayonets that came back to AUS and NZ after the war to end all wars, I have one Enfield nearly the same but with NSW stamped on it with the serial number. I have seen quite a few of recent enfield bayonets which are more common but the Lithgowis more of a rare beast as just about all the quillions on them were cut off. As to the frog it appears more of an earlier pattern IE boer war or the british WW1 webbing for Kitcheners Army. as some one said previously though try the edged weapons forum as they would be able to shed more light on it. This i would also be interested in.
