Edge Malkin? Vases

I have 2 vases which stand 5 inches high. They are a blue and white design. Working from the base upwards the design appears to be mainly blue with leaves and flowers in a geometric design, topped by "stars" in a geometric design,then dark blue toppped by a thin circlet of gold. Above this gold line to the base of the lip is a design of what looks like fine tree branches with blossoms & leaves in blue against a whiteish background. These are stippled with gold. The rim is a paler blue and is also stippled with gold. Inside the vases are ivory in clour and have some crazing. The base of the vases have a printed mark: what looks to be a greyhound sitting above the word "trade mark", underneath that is a ribbon with the words "Edge Malkin & Co", underneath that is "Burslem" then under that "Perth Spray". There also looks to be a circle with 4 nodes pointing outwards and a "c" inside. Also on the base, 1 Vase has "41" in gold and a printed "2". The second vase has a "41" and a "5" in gold. The printed mark on the base is not terribly clear. I have no idea whether these are genuine Edge Malkin or their value. Any advice would be greatly appreciated.
