Listed by the Waltham Machine Tool Worksas a "Milling Stand", this unit utilised not only the headstock but also the compound slide rest from one of their precision bench lathes. The knee could be fitted with either quick-action lever or screw-operated feed. It was designed as a very high-quality, precision machine tool on lines very similar to those of  Pratt & Whitney, Waltham, Rivett and Cataract - where the head from one of their Bench Precision Lathes was employed  in a similar manner.
