If you go on the Gata road, through the town and out the other side, some little distance outside the town on the LHS is a tile warehouse selling all kinds of discontinued and leftover. Also before Gata there is a Rastro on the RHS where you may find something.
However, unless they are an exclusive handmade product, I would not be sanguine about finding stocks of commercial tiles from so long ago. Can you see a manufacturer’s name or ID of any kind on the back? In which case you could send a photo to the factory and ask them.
