Hi, everyone! About February, I received a stayglow-scaled Climber. Today, as I was looking carefully at it, I noticed that it did not had the pinhole; Was under the impression that all latter 91mm sak's had it. Am I under the wrong impression?; if I am, from where should I measure to have a go at making one, and what that/those measurement is/are? The timeframe for returns have expired, so I'd rather try adding/making it. Thanks in advance, as I'm a real newbie to saks ( this is my second to my Spartan!).
