1934 edition of Gear Calculations and Cutting, #185, by the International Textbook Company of Scranton, PA. This was a mail order degree company which provided certificates in a variety of mechanical and industrial fields. This would have been just one of the courses required for certifications. These books were designed for at-home study and are complete with instructional text, mathematical formulas, diagrams, charts and graphs to illustrate concepts. An interesting look back at engineering from nearly 100 years ago.
Vintage estate find, please see photos. Overall in good condition. Pages are intact and binding is in good condition. Minor wear to cover, especially to corners, as expected for a book that is nearly 90 years old! In nearly new condition for age and would be great for study or display.
