This is the fourth in a series of “Photo Log” books it continues the record of (260). It provides a continuing record of optical and SEM photographs requested by members of the engineering staff. Data recorded included; photo #, mount style, date, magnification employed, description of the device or task, and the requesting engineer’s name (the customer). Many of the photographs are mounted in the respective engineer’s notebooks. These records could be used to identify the products and type of analysis being undertaken by the customer engineers during this period.
