Mission oak Revolving Bookcase. This is in very good original condition and larger than most of the revolving bookcases that I usually come across. There is a trademark stamp on the underside of shelf that reads: DANNER. Measures 26″ x 26″ and 57″ Height. The shelves have clearance 10″, 11″, 11″ and 11″. Each shelf is 16 1/4″ wide and 7 1/2″ Depth. Circa 1910.
