Tele Vue 3X Barlow for telescope. Has some dirt on the ring that the screw is attached to. The screw has been broken but a little bit of it sticks out. You could probably unscrew it and get a new screw for it. As a result their are scratches around the area where the screw goes in and out. Some scratches on the silver metal part from inserting into telescope but it's not too obvious. Also missing cap for the side that is closest to lens so only has one cap. The lens has no scratches and is clean. 

See images for scratches and message me for questions

Thank you :)
