This is a charming tiny little child's night light from the late 1870s. It is an oil lamp. I do not have the shade but the burner is there and is in good shape. There must have been some competition back in the day from companies trying to out do each other in sales, same as these days. There were a large series of these little lamps that started to be manufactured at that time, each with different names embossed in the glass. This particular one is embossed around the body of the lamp: "Little Harrys Night Lamp" . On the opposite side of the font: "L. H. Olmsted New York". On the base, embossed very faintly around the base are 1877 patent dates in March and April. The lamp with the shade, is shown in the first volume of Ruth & Fran Smith's first volume of mini lamps: "Miniature Oil Lamps", Figure 15. There are no chips or cracks but the base mold is pretty crude with a little extra sliver of glass on the seam line where it joins the base, leaving a little indention on the foot edge in one spot...probably an older mold. The measurement are shown in the pictures. It is very small, only about one and three quarters inches across at the widest part of the font. . If you like mini lamps of this type I have a few more incomplete ones that I will be listing from time to time at modest prices as I continue disbursing some of my lamp parts. Check my shop for other items of interest and send an email if you have any questions.
