Newall Jig Borer Models No.1,  2436 Mk. 1 and Mk. 2 and 2443. A complete Data Pack. The Newall No. 1 was renamed the Model 2436 and then, with just a greater table capacity, as the Model 2436 Mk. 2 and then re-numbered as the Model 2443. As many parts were carried over from one model to the next, four editions of the Operating and Maintenance Manuals are included together with Parts as Sectional Drawings and copies of the Maker's Sales and Specification and Accessories Catalogues. Includes the separate Operating Notes for the 1520 Airmec Jig Borer. 250 pages.
