Picked up another WallStreet II, (Sierria) and as I suspected, the nib on the nose cone can be removed simply by inserting a 1/4" rod, holding the nose cone assembly in you hand and whacking the rod with a scrap piece of wood, the nib simply pops out, and the black nose cone can be wiggled off the center ferrule, it is no longer glued on, the nib holds it in place.
With the tube that is pressed into the ferrule, it is much more easy to chuck up the ferrule and support the end with a live center, and turn the ferrule shoulder down.
