We have acquired several early electrical equipment catalogs. This is an ORIGINAL 1935 Martindale Maintenance Electrical & Mechanical Equipment Catalog. This company is over 100 years young and still going strong. This manual contains neat illustrations as well as having interesting information on the wide varray of equipment that Martindale was offering back in the day (SEE PICS). This catalog contains 40 perfect pages and is in FINE overall condition with NO tears or tatters. Very scarce. FREE S & H. Thanks for viewing.............Triple K
