We moved in to a new home that has tile marked "MADE IN ITALY" with a "T" a "2" and an arrow down throughout all of the living spaces. It's been kept in immaculate condition and we thought we'd leave it as-is while renovating around it, however we've noticed a handful of cracked tiles due to the house settling and need to locate the manufacturer or find a way to purchase a good amount of replacement tiles. Do these markings mean anything in terms of identifying what we're dealing with? All help is much appreciated!
