As part of my obsession with machine tools I'm on the look out for any old brochures on cnc machine tools. In particlar the early conversions of manual machines such as those done by Harrison, Colchester, Hardinge, etc as well as milling machines, borers, etc. I'm aware of the lathes.co.uk website but this only covers manual machines not cnc machines. Also any old tool catalogues preferably with machine tools.
