This is an old coal-oil lamp. The inscription on the little knob says "The Mantle Lamp Company of America Inc". "Model No 9" "Aladdin" "Made in USA Chicago". The metal lamp part stands 12" high. The shade stamped "Pyrex 1980" and is 6" high. Total height is 18" although any standard coal-oil lamp shade would fit. It is a well-worn silver finish over copper, with the copper showing through in many spots. A lovely display piece that could likely be used if needed!
