[cityone]

HI, I,m looking for a tile which is not in stock anywhere anymore. It was made by British ceramics. (who have gone out of business) The tile is a Laura Ashley tile, it's a ceramic, (250mm x 500mm) white and called "cottonwood" the tile code is = LA51454, i have tried all sites and have had no luck. If there is anyone on here who can help i'll be very grateful. Thanks in advance for any advice.
