Alright I posted I couldn't get this open and now I have looked at it a bit, and noticed lil holes above the pins. I dunno how many there are but here's an idea of it. (I put the lil red holes aviously, but look arnt the pins suppose to go in the wholes? Why are they above them?)
Here:
Well there I haven't a clue unless this is broken or the cylinder turns all around.
Thanks
