Hello, I'm trying to find out more about a plate I acquired recently. It has a 'Canton Opaque China' pottery mark on it with pattern number of 1016. I can only find two other instances of this pottery mark online and both (US) sellers are attributing it to Elkin, Knight & Bridgwood but the mark isn't in the list of EK&B pottery marks on the potteries.org website. There was an EK&B pattern called Canton Views, with a different pottery mark from this one. Is anyone able to shed any light on this for me? Do you know who the manufacturer was? Many thanks Katherine
