SammiI got SZ0030 with the same on the box. Mass production errors like that can be worth extra money to collectors. Dont feel too gipped. Honestly you got a knife no one else has likely. There may not bEe a box numbered like that. You kind of lucked up. The longer you keep it the more it can be worth. If there isnt a OZ0127 box out there the error just makes it even weirder. You can always trade it in I guess but I would try to find out more info.
