The nose cap is not on a rifle. It is just one of a few loose parts that I came across. The serial number has been scrubbed and the wings are are factory milled. I have never seen one marked like this. It looks just like an early Lithgow nose cap but there are no Australianicon stars anywhere but it does have a broad arrow. The markings are so small you can only read them with strong magnification. I also have one that the bayonet boss is blank, Aussie stars on the front of the wings but no manufacture stamps such as MA or BA etc.
