Anschutz sporter on 64 action?

I bid on and won an older Anschutz sporter built on a single shot 64 action, I honestly didn't think the minimum bid was going to be a winner. Long story short, now it is mine, and i am jonesing for it. I was hoping somebody here could tell me just what it is that I have acquired. Apparently it doesn't have an official model number, and was "not originally sold in the USA". I was hoping one of our resident gurus might shed some light on this rifle for me.
