Does it look loke this? If so, it's a 15X Unertl Ultra Varmint scope. I don't remember the amount of change in the micrometer-style adjustments. What I do know is that if you want the POI to go down, turn the elevation adjustment down. Reverse if you wnt it to go up. If you want the POI to move to the right, turn the windage adjustment so the back of the scope moves to the right. Opposite is true if you want it to move to the left. Remember this----when you want the POI to move one way or the other, move the rear sight, or in your case, the rear of the scope tube in the direction you wish the POI to move.
You may be able to get additional info if you do an internet search. J. Unertl was and probably still is in the Pittsburgh, PA. vicinity. They may have a web sight.
