Browsing in the new GTS for matching ring holders and trinket sets I came across, an advert ( see Mysteries - Research - Adverts) of Baronial Glassware. Later I found back this discusssion.... Well, here I am with a photo of the ring holder of that set. It mesures 11,5 x 8,5 cm. Anne, feel free to use the photo for GTS, although we don't know the manufacturer yet.
