This is a scarce miniature lamp in clear glass with frosted font in the Fishscale base pattern from the Dalzell, Gilmore and Leighton Company of Findlay, Ohio.   The lamp measures 4 3/4" in height to the top of the font and 9" to the top of the chimney with a lovely brass burner and clear glass chimney.  There appears to be a ground chip removed from the underside base of the lamp - where it sits on the table.
