Hi Slicksteel ,

This is Artemis from Stigma. First we have the outer control thumbscrew, then the inner adjusting screw, then the needle-pin, and finally the small dampening o-ring.
Please note that in the picture of thejackco you can see a small piece of black rubber this piece of rubber must be squeezed inside the inner adjusting screw and not to be separated.
Artemis
