Hi there, does anyone know the manufacturer of the glass bottle used by Floris London for their room fragrances? The mark on the base of the bottom is a B in a diamond. I’ve found reference to Boyd glass, but they don’t specialise in bottles. I’d love to know who makes this bottle. It’s still being used, so it’s a trading firm. Any help would be gratefully received! Email me for a pic of the mark, as it won’t let me upload it. Best, Tom.
