David,
Yes, they are the same. From the title page of the volume I have: "Reproduced by photo-lithographic process for emergency use from BRITISH AIR PUBLICATION 1618".
My Volume J is green, with no band across it, and says "RESTRICTED" on the cover and title page. The only date I can find on it is the year 1941.
The title is "ASTRONOMICAL NAVIGATION TABLES".
Stan

I have a Volume J (latitudes 40º-44º) of HO 218, but I have never played with it. I didn't acquire the book (at a used book store) until well after we discussed 218 here back in 2011. Was 218 ever popular for marine navigation? Stan

Was HO218 the same as ‘AP1618. Astronomical Navigation Tables. Prepared by HM Nautical Almanac Office on behalf of the Air Ministry’? I have Volume L Latitudes 50°-54° North and South (rescued from a dustbin)? It has an orange/yellow band across the cover similar to the yellow band across AP3270Vol 3. It appears to have been printed in November 1943.
I’d be interested in two things. Does the HO218 version use the word ’Astronomical’ or ‘Celestial’ in its title? Did the various volumes have coloured bands on the cover? If so, were they all orange/yellow, or did each volume have a different coloured band? DaveP
