My Super X 1 came with a white line spacer. It is shown in the exploded view iin the manual and has a part #. It's a very early standard field model with a pacmyr (sp?) Pad. I have recently rediscovered the joy and gratification of shooting it (at targets only)! I also decided it looked a little beat up so I lightly ran a little 0000 over it and the wood cleaned up beautifully (barely touched it!). I cleaned the edge of the spacer while I was changing the buffer. It's only an eighth thick, so I may gaze at it without. The wood and pad are a little proud at the spacer and always have been.
