This item is a ROTARY ECLIPSE BAR SCREW. It is a fabulous addition to a wine bar. This is the creme de la creme of bar screws. The screw is operated by pressing the wine bottle against the collar and turning the handle on the side of the cork screw and out comes the cork. The base is mounted to the bar surface by four screws. This is a heavy duty gadget both literally and figuratively as it weighs in at over 11 pounds. The base is marked "The Original ESLIPSE No 9014. These were patented in England, France, Germany and the United States. We acquired it in the UK so chances are it is English. The screw measures 16" high. The screw shaft is 17 1/2" long. This one is in excellent condition and works smoothly. We don't find this one very often and it usually disappears at the first show that we take them to as it us very desirable and sought after by collectors, wine enthusiasts and decorators.
