The magnification level does not seem to be marked on the binoculars body, but by comparing this item with other binoculars, it looks that the magnification is around 8x or 10x. This information is for reference purpose only. (There are some very small inscriptions on the side of the top prism plates, but these are scarcely legible).
The lenses have been cleaned where possible. This item is in good working condition for its age, no chips or cracks on the internal / external lenses, and the binoculars give a clear image. Please view the photos for more details.
