The World is Made of Glass Ltd. has dated this piece to the 18th Century.

The glasses are in excellent condition for their age. They show age related wear and tear to the rims of the feet consistent with some 270 years of use. They have rough pontil marks on the undersides of the feet.

The glasses have rounded funnel-shaped bowls measuring 5.5 cm (2.2 inches) in diameter at the rims. The bowls are engraved with an open six-petal rose and a closed bud representing the House of Stuart and Bonny Prince Charlie respectively. James Stuart (The Old Pretender) died in 1766 and the glasses were probably engraved after his death, hence the absence of the open bud that appears on earlier Jacobite glasses. The bowls are also engraved with the initials "WH". The bowls sit on double series opaque twist stems consisting of two lace twists wound around a central column of two twisted cords. The stems lead to conical feet which measure 6.8 cm (2.7 inches) in diameter. The glasses are 14.8 cm (5.9 inches) in height. Dimensions vary very slightly from glass to glass. There are no chips, cracks, scratches or any obvious signs of restoration. There are collector's stickers to the undersides of the feet. One of the glasses has a small black inclusion behind the engraved "H" which dates from manufacture.
