Carpet tiles (Kellington DN14)

This is a very long shot... A few months back someone posted some carpet tiles here that we gratefully collected. We have finally finished our refurbishment work and have figured out that we are roughly 10 carpet tiles short. They are black with blue stripes and we collected from somewhere in Leeds. As they still had a lot of work to be done and I can't find the same kind of carpet tile anywhere, we wondered whether they are still active on here and whether they would have a few carpet tiles left please? Thank you for reading
