Antique Plum & Atwood Parlor Lamp Circa 1880-90's

Up for auction is a circa 1880-1890's Plum & Atwood Oil Parlor Lamp. It is signed on the base "P & A No. 23". The lamp measures 16 3/4" tall to the top of the shade and 19 3/4" tall to the top of the chimney. It features an embossed decorative iron base, hand painted glass font with yellow and magenta roses. The brass burner and gallery is signed "Climax Pat. Jan.21.90. Made in U.S.A." The assturol wheel cut shade is 7" tall and about 6 1/2" wide with a 4" fitter neck and a crimped top rim. The only flaw I see is a stress crack in the brass ring that sits between the base and the font, which is normal for a lamp of this age. I believe it to be all original from the base to the burner, but I'm not sure if the decorated assturol shade was original to the piece. A little clean up and this beauty is ready to display or fill with oil and burn. Feel free to contact me with any questions. Thanks for looking & good luck bidding! Joe
