Sourcing old floor tiles

I have a beautiful ‘French’ kitchen that has a checkboard - like floor of black and tiles, 10cm (4 ins) each side. I now want to match them in my new extension.

I haven’t been able to find a source for them but recall once stumbling into a hardware store that had a range of older stock.

Has anyone come across such tiles or a store that keeps such tiles?

Keep an eye out on Le Bon Coin. Sometimes people renovating their properties put such materials on the site.

We had the same colour/style matching problem. We went off to a couple of local ish tuileries with exact descriptions and and old tile we found in the attic. They reproduced 3½ doz for us. You cannot see the join.

Good plan - anyone know of any tuileries in Finisterre or nearby?
