Practical treatise on milling and milling machines

This book serves as a general Manual for all the milling machines manufactured by Brown & Sharpe, particularly those built between WW-I and early WW-II. B&S did not produce individual operators manuals, this book in various editions over many years served the purpose for all their mills. Extremely worthwhile book if you have B&S equipment though some of the information can also be found in Machinery's Handbook.
