Churchill NB Surface Grinder: Comprehensive Maintenance and Operating Manual and Parts Manual as Sectional Diagrams and Exploded Components for both early and late machines combined from three manuals, only one of which carried an official makers designation number, and listed by us as Edition A, B and C

PLEASE NOTE: this manual is not for the very first model - identifiable by the drive motor mounted down at the left-hand side of the machine at floor level and the right-hand control wheel set face-on to the front instead of angled to the right as on later models.

Included are the following diagrams and drawings:
