Bag age/cross strap type?

I can't remember when I got my bag and I need a new cross strap.. I *think* it was sometime in the mid-90's and I'm aware that the design got changed in 2003. Can someone help me identify the age of my bag?

The strap has a male clip on one side (I think - I don't actually have the thing anymore) and there's a female clip attached to the shoulder strap, and a little slidey thingo attached to the bag near my left hip when it's on me. No D-rings, nothing else.

Thanks, guys.
