Telephone Instrument Maintenance Manual- ITT Telecommunications Division (1970)

Description

This manual is a collection of service data put out by the Telecommunication  Department of ITT which covers many classic rotary dial telephones to early touch tone phones. It contains data from mid 1960's to late 1970's.  The contents were produced by the engineering department and given to the field service personnel as individual publications, as new products were developed.  The service men cataloged each product as new designs were made available and were used while in the field. The manual is in good condition- minimal cover wear.
