It would seem their handiwork came after taking the photos. Since even from poor quality image, the punched crack and abrasion above the hole should have been noticeable in the photo.
Did the pair you got match the s/n of the pair he had pictured and/or does the arm finish match the orbital finish... or did they pull a switcheroo on you and send you a different pair?

None of the pitting looks to be shown in eBay pic either - it looks like he swapped out bridges.
