The manual is missing the first 15 introductory pages (81 pages are the remaining) and was originally printed on heavy-duty lavatory paper - hence the quality is only just acceptable. However, it includes - mounting of high-speed spindle and vertical head, angular setting and swivelling settings of table, backlash elimination of longitudinal movement, double swivelling sliding spindle high-speed head, slotting attachment, adjustments: belt tension, play in universal head spindle and horizontal spindle, knee and cross slide locking devices, gib strips, steady bearings, lubrication, Parts Manual and an electrical diagram.  NOT up to our usual high standard or reproduction - but the original was pretty terrible....
