The weight underneath the picture (170) is the scale weight. Its got faint ink inside the rim.
This is the back of the white hornet (left) and white stalker (right). And yes, I am interested in all 3 strikers. Could I get pictures of them please? I'm also interested in that River, if you want to trade all of them. Just let me know!
There just isn't enough info for me to identify it. They have used that bar stamp on a lot of discs. A lot of Millennium discs are very similar looking, so it's almost impossible to tell them apart in pictures with no other clues. You are better off finding somebody local who can hold it and tell you what it is. Sorry, man.
