Yep, ran into this years ago when re-rigging Insatiable I prior to our first departure. Got new cones, couldn't get things to
work right. Had a neighboring rigger try... he couldn't either. Called the parent company in the UK, and after a lot of expensive humming and hawing, I mentioned that the old cones were brass or some other yelllow metal, and could I re-use them? "OOOHHHH, brass cones" they said, "those are the OLD model Sta loks, and the new cones don't fit" And even then (1985) you could not get the o ld cones. They did sell me the new
parts at cost, but still... and NO ONE in the
SF bay area knew about this change over. Pretty odd... and pretty expensive!
