Set of 3 vintage catalogs from the Commercial Shearing & Stamping Company of Youngstown, OH. Includes catalog H-3 on commercial hydraulic cylinders, catalog H-4 on commercial hydraulic pumps & motors, and H-12 on performance rated valves to control and direct oil hydraulic fluid power. Catalogs are 56, 60 and 92 pages long respectively. They are undated but I would estimate them to date from the late 1940's-early 1950's. All have limited color printing throughout as shown. Lots of information on size and performance of parts, and a few photos of vintage equipment as well. Illustrations and/or graphs on nearly every page.
Vintage estate find in very good condition with only minor wear, but please review all photos. Some light wear to cover corners but well bound and pages are intact. Overall in great, readable condition. Would also make a fun display piece!
