Item is a device to focus an image on the easel of an photographic enlarger before exposing the paper. It consists of a magnifier and an optical tube to look down and to see a portion of the projected image. One places the unit on the enlarging easel and adjusts the enlarger focus knob, until fine detail such as grain comes into focus. This ensures a properly focused image. The locking screw for securing the ocular in place is missing.
