Preview lever Copal shutter

I am trying to figure out how the black plastic tip on the preview lever of the newer Copal shutters can be removed - only the tip, not the lever itself.
While the tip of the aperture lever is fixed via a small screw to the actual aperture lever and can be removed easily, I cannot see a comparable screw on the tip of the preview lever. I suspect it is simply pushed fit on the metal part, but I am not 100% sure as it sits tight and I have no clue in which direction to pull. Obviously I don't want to break anything by using force. I would like to remove the plastic tip because it slightly gets in the way of mounting the shutter on a camera.

I have a Copal 1 with a triangular shaped preview lever cap. It is attached via two screws on the rear side of the lever. Other possibilities are the cap is threaded (screws) on or is bonded in place.

If your preview lever is contacting the lensboard when the lens is mounted, just shim the lens away from the board a bit. If it contacts the front standard, you might be able to mount the lens so the preview lever points to one of the corners, giving it a bit more room. It's awfully convenient to have the tip on there...
