Hi  Robert.
                  I was a Navigator in the '40's and 50's and used them.
Here are quotations from my 1943 copy:-
   "Compiled by L. J. COMRIE, M.A., PH.D., Late Superintendent, H.M. Nautical
Almanac Office.

Preface    These tables came into being as the result of suggestions put
forward by Lt. Com. P.V.H. Weems, U.S.N.  (Retired during his visit to England
in 1936...
   One particular source of encouragement was the fact that a chapter of thee
new edition of THE ADMIRALTY NAVIGATION MANUAL  was devoted entirely to a
description of the tables.  ...
     It must be made clear that the only originality claimed in the three main
tables (I, ii and iii) is that of arrangement, typography, accuracy and
explanation.  These same figures can in other places, but not in one place , or
with a single latitude on each page.   not exceding the ALMANAC in bulk,
inexpensive , and yet affording equally well the saving that follows the use of
an assumed position or the advantages  of a dead reckoning position when
required.  ...
it has proved fortunate that the requirements of sea and air navigation have
not conflicted, and so can be met in a single volume, without detriment to
either.  ..  the U.S. NAVY,  who generously gave permission to utilise material
in U.S. HYDROGRAPHIC OFFICE PUBLICATIONS Nos. 208 and 211."

On a nice morning in the tropics I could usually manage to take five or six
sights before sunrise and have a position on the chart and down for a shower
before 7am.. Of course in those days there was nothing but pencil or pen and
paper and we didn't get too fancy with a cocked hat.  They gave you all your
information and were good for all seas from Milford Sound N.Z. to Yokohama, L.A
.  Villefranche and Oslo wthout crushing too many crabs.  I bought my present
copy in Halifax, N.S. about 1978, after presenting my original to a yachting
lawyer in lieu of his fee.  Cheers, nsg
