Tascorama red dot gun sight

[JerryM]

I have a friend who found a Tascorama red dot gun sight among items he got from an estate sale. He doesn't know anything about it, and neither do I.

Does anyone know anything about this sight, what batteries it takes, and where he might get an instruction manual?

Thanks,
Jerry
