This might be an American Optical brand but not sure. The eye pieces are marked 181 and 191 which we believe to be American Optical.
Power adapter is not included, you will need a 9V Adapter with barrel connector ,center positive. We tested using our bench supply, light is good.
Overall this attachment appears in good shape along with the optics.
