1903 Welsbach Gas Lamp With Super Rare 20 Inch Flat Milk Glass Shade

I have not found a 20 inch diameter flat milk glass shade in over 15 years. For collectors they are considered a Holy Grail of early industrial lighting. The lamp is signed Welsbach Lighting Company and has been wired to take four E26 bulbs… 20″diameter x 12″… $2200
