Scarce 1919 Practical Treatise on Milling and Milling Machines by Brown & Sharpe Mfg. Co., Providence, RI.  Softcover, 334 Pages.

Also an accompanying Brochure on Differential Method of Indexing.  11 Pages.

The Textbook is originally from an Apprentice Course.  Most existing copies are of much later publication dates.

The Treatise is in very good condition – clean and tightly bound.  Cover is good with just some spotting along the front.  The Indexing Brochure is good though the last page is separating from the stapling.  Both measure 6” by 9”.
