Thanks Neil. Glad my memory is correct .... I'm getting old y'know ... :p It makes sense that the mine mainly quarries stone for industrial or decorative materials. The same with Ardennes IIRC. The hones being an adjunct of the main marketing. I guess , in this day and age, it wouldn't be a viable business if hones were all that the quarry mined. That darned safety razor came along and ruined the market. :shrug:
