This is a generic 25mm Plossl in very nice condition. Optics are clean and clear with very nice multi coatings. This appears to be manufactured by the same folks that make the Pro Optic units. It has the red rubber ring at the top of the barrel. Very clean with only very minor set screw marks on the lower barrel. Feel free to eMail with any questions. $25.00 plus shipping (CONUS ONLY).
