My blue otg I picked up used is speckled like that. I will have to go look at the vent to tell you what the vent code is. Mine might not be quite as much as that one though. I was kinda diapointed when I went to look at it before purchase but it grew on me it looks good from a three or more feet away cause it is so dark but up close you see the speckles and its neat to see that too.
