Beautiful ornate Lunkenheimer Co. 5 chrome plated pump oiler in very good condition. The oiler was made in Cincinnati, Ohio. Unfortunately, the glass is plexiglass. The chrome is wearing through to the brass in a few places. Everything moves and works as it should. The mounting threads are 3/8-inch NPT. Not sure if this was for a steam engine. Hit & miss engine or very early machine tool. It stands about 8 1/2 inches high and is about 3 inches in diameter. A beautiful and hard to find addition to your oiler collection. Please see my other auctions for more engine parts and collectibles.
