Hardinge - Cataract. Unfortunately, there was never a "Manual" for the early Cataract lathes and millers - but there is a wonderful full-range Catalogue showing all the Precision Bench and Screwcutting Lathes, Milling Machines, Automatic Gear and Pinion Cutters, Drills and the full accessory range made from 1900 to the early 1930s.
