This was stored in a box labeled Mogey. From what I can figure it is a
replacement finder scope lens. It is in a brass cell and has an
aperture of about 1.4" and a focal length of about 7.5". The cell is brass and has a
lot of patina on it but I am not sure if it is painted black. Glass is
vintage but in nice condition.
