thanks for that,i never noticed... there is a pic of one that has the same maker,same month,same year as mine,but with the hook removed. IT is in the thread about the NZicon sold out of service marks on 1907s.. the year stamp on this example appears to be identical to my one.. but thanks for pointing that out. lucky for me there is a military arms fair this weekend in melbourne, im taking this thing with me to have it evaluated by other collectors and probably sell it too.
