precision ground flat stones.. not surface plate, lapping plate, flat reference surface for measurement etc etc... as I said, more information is available if you look at the links.

The two places I know of are Stefan Gotteswinter (won’t post to UK) : Precision Benchstones – Stefan Gotteswinter
and Kinetic Precision (he’ll post but expensive and it would be better to get from somone more local I think): PFG Stones - precision ground flat stones for toolmakers, machinists...
Hi, I am currently looking for some myself and wondering if you found anyone UK-based, or that would supply to the UK for a reasonable price.
I searched for Luke Rickert and found an engineer in Norway (not France - maybe he moved), but I cannot see any mention of stones.
