The company is called Ceramica Enea. Vulcano Negro is the style/colour. I think you are probably on a hiding top nothing. The only way you might be able to source these is by talking to any of the large commercial tile distributors in the UK - use Kompass or Yellow Pages. As you probably know, very many tiles come into this country from Italy and Spain and the major distributors source from many suppliers. There (probably) no point talking to the shop staff - you need to try and talk the buyers in these organisations. I have tried this before with limited success only, when I have been trying to get competitive quotes from a second source when I know the exact tile and manufacturer as a means of beating down the price through competition. There are literally hundreds of companies in these two countries. Good luck.
