There is a small chip area near the edge of the front lens (as shown in the last photo), but this is not visible when looking through the scope in normal way and it does not seem to affect the light transmission and performance of the scope. No damage to other lenses and all internal lenses have been cleaned. The telescope gives clear images.
The small sliding eyepiece cover is missing.
Please see photos for further details.
