What is kind of Mini Bike is this?

Wow that was fast!!! Is this worth restoring or should I get ride of it. I picked it up becuase I wanted the engine that was on it for my 1969 Rupp. are parts around for this? Also I just joined yesterday so please bear with me on my min bike knowledge.
I have owned 3 of them but have never restored any of them I just sold them as rollers. I have heard they are some of the nicest riding bikes because of the frame design using the back half of the frame like a giant swingarm. Restore it . You can always sell it if you dont like it. And it is a fairly common bike so the parts are easier to come by.:thumbsup:
