Do any of you have experience with the old Scripto Vu Lighters? The lighter had two parts: 1. a reservoir that held liquid lighter fluid, and 2. a second reservoir (probably filled with cotton) which fed the wick. When the flame burnt low, one would press a button on the side and lighter fluid from the first reservoir would saturate the second. I think that I remember that they may not have been as windproof as Zippo lighters; but, one did not have the evaporation problem of long term storage and could see how much fuel remained. Vu Lighters can still be found on eBay.
