I cannot find another of this design and the most similar is Bouton Dor. It has a similar triangle shape to that design but each side is at different levels showing off the shape perfectly. I have posted photos of any marks/scratches that I think may be present, however, none are very visible without very close inspection/zooming in. Photo 6 shows the Baccarat etched. Photo 7 shows zoomed in scratch.
Photo 8 shows base with etched Baccarat trade Mark. It has the most beautiful crystal glow and has sat in our cupboard for possibly 30 yrs, perhaps being used once! It has the double baccarat etched and etched stamp on base. It measures app 17cm at highest point and 13.5cm at lowest and measures app 12cm across the top (widest part).
