I know that he used to go to tips and cut up any likely looking stone he found. Now he obviously sells Inigo Jones hones and I am sure he has a deal with the owner of another quarry. The so-called vintage thuringians originally came from a large purchase of hones from european authorities (like closed machine shops, labs, that sort of thing), lord knows where they come from now.

The purple, grey, dark grey and green slates are all available today, from a lot of welsh quarries (I live in Wales nr Snowdon national park for part of the year) so there is little danger of them running out. However, things are cyclical and I expect that supply will outstrip demand and the price will be lower and lower until it is no longer profitable.

What goes around comes around, they say.
