Yes, I'm fairly sure that it's John Deacons. I have a sort of almost identical bowl, the colours of the two main flowers in mine are reversed, the centre cane of all the flowers on mine are all black and are made up of many thin black rods, but,there is the same label to the base and my bowl has an "St K" cane at the base of the flower stems.
I'll post some pictures later when I get the chance.
