This is a very nice and quite scarce double fingerhold glass oil lamp.  The pattern is a ball base with thumbprint stem and swirl font by the Dalzell, Gilmore and Leighton Company of Findlay, Ohio.  The lamp measures 5" in height to the top of the font and 13 1/4" if you include the clear glass piecrust chimney.  The lamp has a great #1 brass burner stamped "Socony No. 1".  The lamp is in excellent condition.  A very hard to find double finger hold Findlay lamp.
