the tulip bowl finely engraved in diamond-point, probably in Holland, with the crowned royal coat-of-arms of Prince William IV of Orange within the garter, all within a tied pair of orange tree branches bearing the arms of the Seven United Provinces, the solid base over a teared drop-knop and short plain section, the domed foot with folded rim

For two almost identical examples of this rare form see L.Bickerton, Eighteenth Century English Drinking Glasses (1986), pp.72-73, figs.85 and 86.
