This is a gorgeous ruby cut to clear Sandwich hand lamp with a one tube fluid burner that fits a number 2 collar. The glass neck inside the collar was designed for a number 2 collar and the lip is firepolish just as it should be. The cutting pattern is a quatrefoil and punty cut design. This very same cutting pattern can be seen on the green cut to clear castor bottle I also have listed. Height to top of brass collar is 5 inches. This is a heavy well made piece.
