Handbook for Fire Control Instruments 1909

Handbook for Fire Control Instruments


Document ID
Ja 345a


My copy of this is a set of digital photographs of copy number 173 residing at the Admiralty Historical Library in Portsmouth. It bears a promulgation note dated 23rd February, 1910, and mentions that it obsoletes a 1906 edition.

The contents of this edition are helpful in dating the adoption of various equipment, especially when used in conjuction with other sources, such as the 1914 edition of the same handbook.  Torpedo drill books would also be helpful cross references.
