Old fashioned 'oil lamp', a 1970s or 80s piece made in an antique style, wired for electricity. I didn't see a makers marking on this... maybe Lamplighter Farms? Love that cobalt blue color!
This measures about 10 1/2" tall to the top of the light bulb socket, about 19 1/2" tall to the top of the glass chimney when in place. Works fine.
