This is a lovely Victorian miniature lamp from Stevens & Williams Glass.. The brass burner is dated: "PAT. FEB'Y 27, 1877" as shown in the close-up photo of the burner. It's all original in excellent condition, but does have some minor chips to the top edges of two of the applied petal feet. The glass is clean inside and quite beautiful. Overall height with the burner is 5-1/4" by 4" round.
