TNA ADM 186/667 154

10cm x 16cm


I have an actual copy of this small green handbook.  Mine is marked "USS Pennsylvania" and "CinC #6" in pencil in the inside jacket.  The USS Pennsylvania did not venture over to join the Grand Fleet as part of the US's 6th Battle Squadron, but I'd welcome any interpretation of these jottings.

The book is handy and varied in content.  Some portions of it (notably, the wireless telegraphy portion) appear to have little actual bearing on military application for the fleet, being prized from Post Office practice boilerplate.  The section on W/T use between army and navy seems more on the money.

One curiosity is an inserted and separate card with color images of RN flags and pendants, special Morse characters extending the alphabet, and a sheet with semaphore positions and the basic Morse alphabet.  This is rubber stamped "Operations-Aviation Planning and Information Section" and hand-labelled "Stencil #141" on reverse.

There is no table of contents or index, as such, but I've noted the main sections below


Chapter I. -- Semaphore 3

Chapter III. -- Flag Waving 14
