I am trying to find out if this is worth keeping or not. It has been in a box filled with a sweet smelling fuel in my garage. Any information about the date of manufacture would be great. It was in my grandparents possesion for a long time, but since they are gone now I cant get any info on it. It is pressed glass, says Hong Kong on the bottom. The metal is light weight and has not rusted at all. It has the original wick in it, but the fuel has been in it so long I am afraid to light it. I dont know what to clean the metal with so it is dusty.
