Need help on a frame
 

Hey Folks,
I'm a newbie to the site, looking for information about a frame I've had for quite some time.
So the frame is aluminum, it has no stickers or etching on the headtube.
The only marks are on the back drop outs that say "one way" there is a cross as well.
I was told long ago it was a D-WOLF frame.
Can you folks help out and tell me what you might think this frame could be?
Who built it?
thanks
