This is a beautiful clear glass oil lamp.  The pattern is Sweetheart with Frosted font by the Dalzell, Gilmore and Leighton Company of Findlay, Ohio.  The No. 2 lamp measures 9 1/2" in height to the top of the font and includes a great chimney.  The lamp has a small chip on one edge and a minor bruise in the glass at one bottom point.
