I know this is a very long shot but I'm trying to find some cristal tiles from 23 years ago. Perhaps somebody has a few lying around that they have forgotten about.
The tiles are 6 ins by 6 ins with a mottled green colour. They have a series of numbers on the reverse which are 05 03 followed by F1 08 and, from memory are either by cristal or H & R Johnson.
Any help whatsoever would be greatly appreciated.
