Vintage Converted Kerosene Lamp with Ribbed Milk Glass Shade

This item is a vintage lamp that appears to have originated as a kerosene lamp, subsequently converted into an electric lamp. The physical characteristics include a clear glass oil fount (base) with a ribbed or fluted design, giving it a somewhat squat, rounded form. The glass fount sits directly on a wooden surface, suggesting it might be missing a pedestal or foot if it originally had one, or it was designed as a table lamp. On top of the glass fount is a brass or brass-plated burner assembly, which shows signs of age and patina, consistent with its likely conversion. This burner mechanism is now fitted with electrical components, including a twisted brown electrical cord wrapped around the base and burner, indicating its current function. The most striking feature of the lamp is its shade, made of milk glass with a creamy, opaque, off-white color. The shade has a distinct vertically ribbed or fluted pattern, and it tapers upwards to a rounded top, resembling an inverted bowl. The shade is held in place by a brass gallery or fitter that connects to the burner. The overall condition shows visible wear and age, particularly on the metallic components which have darkened and possibly corroded over time. The electrical cord appears to be an older, possibly original, conversion cord, which may indicate its age or could be a safety concern. There are no immediately visible cracks or chips in the glass fount or milk glass shade from the provided images, but a thorough inspection would be required for confirmation. The lamp's style suggests it could date from the late 19th to early 20th century, common for kerosene lamps that were later electrified. The craftsmanship appears functional, with the milk glass shade offering a diffuse light once illuminated, characteristic of the period's lighting aesthetics. The ribbed design of the shade adds a decorative element.
