Original 19th Century Extremely Rare Etched Chimney Detailed Finger Oil Lamp

This antique footed finger oil lamp is a stunning example of the various Oil Lamp designs of the period. The footed base features, intricate detailing especially along the finger area. Check the Photos!!  The glass chimney is an extremely rare Guyer and Calkins from late 19th century to early 20th century. Guyer and Calkins was a Freeport Illinois based grocer and distributor extended to household goods like lampshades, which were likely sold alongside other domestic items. The glass chimney is a pearl top empire style featuring the Guyer and Calkins brand etched at the base of the chimney and still visible, adding to its collectible value. There are also the words "Gold Chord" etched with it. In all my research, if Guyer and Calkins and Gold Chord are both on the chimney, it is stated that "it could be a crossover promo item- though no such example has surfaced in known auctions or collector database." which could make this a very seriously rare piece! No chips/cracks! NEXT DAY SHIP!
