Thanks for those who responded the first time. Now that I have photos I can be more succinct. This is an older style 19mm Tele Vue Wide Field eyepiece, 65 degree apparent field, with the detachable rubber eyeguard and a plastic screw-bolt case. Protostar flocked paper covers the exposed retaining ring of this version and protects eyeglasses from being scratched. The o-ring covers scratches around the edge of the lens. The visible glass is perfect. There is a small nick in the field stop, and it has the usual hairline barrel marks. No dings or dents.
My price is $70 + shipping (firm).
