This is a Mayflower pocket sized monocular with original zipper case. It is J-B231, Field 7.5 degrees, 6 X 15, with coated lens. The turning of the lens for focusing & zoom is super smooth. It comes with an attached string to hold around your neck, wrist, etc. The case has no damage and the zipper works great. Overall, a great little piece for the hobbyist and is without any kind of damage or hard wear. Zoom in on photos for full conditioning details.
