For Holder Experts

I received this today and it peaked my interest in holders so I visited the PCGS holder museum. This appears to be a Gen 2.2 holder but without the 4 alignment pins depicted in the museum. I can see a circle in the obv lower left and half circles in the margins (pins?) for the upper two but all are out of place as compared to the museum example. Only 3 circles appear on the reverse (the upper left one can't be seen in the picture) but they seem larger. It's like a tween of the 2.2 and 3.0. and other than a 3.1, I don't have another OGH to compare. In short, are these circles "pins" and do I have a 2.2? Any/all guidance appreciated.
