Does anyone know who makes this scope?

I got one of these from a friend, who couldn't get it to work.

I figured it out (it requires a special battery) and am now in possession of a working active night vision scope.

The label is worn beyond recognition, the writing almost nonexistent. The lower tube holds a single AA sized 3.6 volt battery. The upper tube holds another of the same batteries and has an on-off-test rotary switch on the end.

The Eyepiece adjusts for eye relief and their are 2 adjustment points. One marked DN (DOWN) the other marked RT (RIGHT) is on the left side.

I cant find any other pictures on the scope online. This one is from Bolivia.

If you know who manufactures this scope or even what it's model number is please let me know.
