...a chip and scratches? I guess it doesn't matter as much with a mirror of this size but it does hurt the self-esteem:(
Yes; I got a real bargain on the 16" Meade dob I used to have because the former owner had dropped the secondary mirror onto the primary and made a "ding" on it. Didn't make any difference optically but it hurt the guy every time he saw it! At 33" I suspect the seller of this one doesn't want to invest in a new mirror just to preserve his bragging rights.

Digruntled worker at Mt. Hopkins Observatory took a .45 Auto shot at one of their mirrors. I don't recall which one but it was in the 2 meter + range. Shot a divit into it - that was it.
Is that Mc Donald Observatory? I remember a picture of an old Astronomy magazine with a couple "gunshot wounds" on the 72" mirror, which had just been sealed with some kind of glue to prevent cracking.
