I was out at my granddad's today, and among other things he gave me this old night vision scope to play with. There are no markings on it. On the right side there is a knob that turns it on and off and adjusts the intensity, on the left side there are knobs for adjusting elevation and windage. It's powered by a 9v battery. It has a weaver mount for attaching to a rifle, and the objective is adjustable. It has a little flashlight shaped thing that attaches to it, which when I turned it on in the dark appears to light things up (I assume it's infrared as it gives off no visible light). Any info would be appreciated
