The reason for those tables in H.O. 208 (also found in Bowditch at least through the 1938 edition) is that in the olden days the positions of celestial bodies were listed by Right Ascension. So to find your local angle you first calculated your local sidereal time and compared it with the RA of the body, the difference is the LHA. See excerpts from NA 1937 located on my website here:

Also see attached pages from Air Navigation, Weems, 1938.

Thanks Kermit. Your analysis seems likely which means that Pub 208 table III is of little use for todays CN sight reductions.
