Stylon 4 x 4 tiles

I'm trying to find some (about 8) shower tiles made by stylon probably back in the 50's-60's but can seem to locate a source. Color is a "robins egg" blue. I've checked a few sites on the web but have unable to find these tiles.

Do you still need some of these tiles?

I'm tearing out some. They are from Stylon and it sounds like the correct color.
