For its age it looks to be in excellent shape, I can't see any dings other then the small gauge in the barrel logo and the bottom key cup looks a little rough. From my understanding is that as far as quality goes it is if not thee best, it is ranked top 5 metals ever made. It should clean up nicely.
I have heard that if they are damaged and you need to get it repaired, it is going to cost you. I would recommend being gently with it.
