The old advertising picture clearly shows my candle sticks but there is no mention of the colour in Charles book only blue and purple, perhaps they are Webb Corbett but something else, or the purple and blue are not agate flambe and something else, it depends on what info he had at the time and examples to hand.
The picture in the book looks the right colourway for mine so perhaps there were three versions or maybe more ?.
Probably people do not know what they have, look at all the Brierley keith keeps finding, a massive variety of shapes and techniques, the local factories copied each other once a new product was made.
