This is a beautiful clear glass oil lamp in a 'squatty' large size.  The pattern is Sweetheart with Frosted font by the Dalzell, Gilmore and Leighton Company of Findlay, Ohio.  The No. 2 lamp measures 8 1/4" in height to the top of the font by 6" in diameter.  The lamp is in excellent condition with a nice brass burner.
