Hello:
Compliments of Noell, I have a third edition H.O. 208, 1931, which says
“For All Latitudes”. Table 1 to 65 degrees .LHA to 90 degrees. Looks like 1929
version. Still 75 cents.

Hi Peter,
I have a Second Edition of H.O. 208, 1929.
Nothing about All
Latitudes on the cover.
Table II d~b ( not d+b and not IIa )
LHA to 90
degrees and latitude to 65 degrees. No higher degree markings.
Table I ( not Ia )
LHA to 90 degrees and Latitude to 65 degrees.
"Price 75 cents"
Inside the front cover are two "cases" with a note "Case I covers the majority of problems (L.H.A between 0 degrees and 90 degrees, or 270 degrees and 360 degrees)" (attached photo)
"Case II ( L.H.A. Between 90 degrees and 270 degrees)
At the L.H.A.
Calculation is "note 13b"
Attached is Notes on Solutiion with 13b that tells you to adjust the LHA to
get back onto the 0-90 degree range.
Regards, Noell
