TitleWandry patent notebook (#260)
DescriptionThis is the third in a series of “Photo Log” books. (They are not numbered chronologically.) It continues the record of (473) and provides a record of optical and SEM photographs requested by members of the engineering staff. Data recorded includes; 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. This information can be used to identify the products and type of analysis being undertaken by the customer engineers during this period.
