scripto lighter

I have an old scripto lighter. the kind with the lighter fluid and flint and the "see thru" plastic view that was popular about 25 years ago before butane took over the world.Well the wick finally gave out and I can't figure out how to change the wick. Does anyone out there have one of these??? ever changed the wick?? They are different than the other lighters and i need some expert opinion. I really like this lighter.
