The inside bottom has Dickens Ware Weller impressed into the mold - a mark that was. The kerosene font filler cap reads: Fostoria Patented Sept. The adjuster knob moves freely and reads Made In America of US. I did no additional testing of the hardware.It is in excellent condition. The only flaws to note is some flaking to the glaze on the rim under the font and what looks like a tight hairline INSIDE the piece leading up to one of the legs. It does go through to the underside. Again, extremely tight and about 2 long. A well sought after piece to add to your collection or décor. Due to the weight of this piece there may be a considerable difference between the post office and Fed Ex. Please see my other auctions this week for many more vintage items.
