Looks legit to me ... it has the Peterson Dublin series 'split P' stamp. Based on the other pipes he's selling and his 100% rating, I would say its legit. He has some other nice Pete's there as well. It looks like he is selling his own collection or the collection of someone else. His inventory is divided between straights and bents all roughly the same types across brands. I noticed some are re-furbished so it is possible he cleaned and rounded the top of the bowl. I think it looks better but that's just me. 2 cents.
P.S. I don't believe that ring is red now, having seen the original pics ... I think its coral or jade but I don't know what year it would be ... check with Peterson. I think the price was fair to good. 68's sell high.
