I always think these 'midnight' coloured pieces are likely to be Dartington, then get them home and discover they're not. Having looked through my book I don't now think this is. The woman at the boot sale said it came from an oldish house when she lived in France, and it may therefore possibly be French. Ground and polished pontil - stopper is also ground and polished on the top - whole thing about 195mm tall. Some wear, but not a great deal, and not marks that I can see. Rather small for a standard decanter I thought, might it have been for a liqueur? Could be Scandi of course. If anyone recognizes the design please let me know, and thanks for looking.
