Entries between 1901 and 1912 on this page with detailed manufacturing records in the notes column, as well as those listing repairs at the end of each year, have information from the Telcon Record Book of Submarine Cables Manufactured and Laid by the TC&M Company. Volume 1: 1850-1912. . High resolution scans of this book were made by its present curator, Alcatel-Lucent of Greenwich (now owned by Nokia), successor to the Telegraph Construction & Maintenance Company, and were provided to the Atlantic Cable website by Allan Green. Thanks as always to Bill Glover for his meticulous transcription of these records. |
