Vixen Telescope Finder. This is the finder scope used with a Super Polaris R150S. Please use this if you are only looking for a finder scope. There is no O-ring, but I used it myself. There are scratches on the main body. When the black part on the viewing side is removed, a chip can be seen. It can be used if attached. The lens shows signs of aging, but it can be used. - Included items: Lens cap, mount leg, 3 screws * No base or O-ring Thank you for viewing. All included items are shown in the photos. I think it is also ideal for spare parts. Thank you.
