Hello Graham - Well, the Alaska Volcano Observatory was established in 1988, so I doubt we've ever had anything to do with an antique lighter. Enjoy your find! -Cheryl -------- Graham Hale wrote: hi from sunny England, ive got a very old petrol lighter it is engraved on one side A.V.O. and on the other side are a persons intials N,A,B or A,A,B. i no its along shot but do they mean anything to you, checked lighter makers none called AVO,tried the web and it keeps coming up with you,dont worry if cant help just wanted to find out history of lighter, thanks graham -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
