Anyone ever seen this scope?

My neighbor got it on a trade gun and gave it to me. It's a 6-24X50 and the parallax and zoom are as smooth as silk and dead on for distance. The lenses are clear as a bell all the way up to 24X and I'm simply amazed at the quality. It is so clear it's amazing. BUT, and now to the kicker, the turrets don't move the point of impact, either up/down or left/right. I'm going to take it apart and see if it can be fixed, but I'm guessing it's toast. But I simply can't believe the optics. It even has a duplex with ultra fine crosshair and a dot in the center, The dot is lighted and it works beautifully. A tiny lit dot for dark conditions. It's really a cool scope, just doen't adjust. I was even thinking of trying to get adjustable rings and go with it that way just to see how it holds zero.
Anyway, probably for the trash, but has anyone ever heard of Airscopes?
