A "three-minute" sand timer with antique bronze finish.  Unfortunately it times out at 2 minutes and 50 seconds and is therefore reduced in price.  New and unused - ex-shop stock.  160mm tall from the table to the top of the mast, and the steel top and bottom plate is 77mm diameter.  Great item for a desk ornament, or a functional item in the kitchen.  Please see photos for further detail.
