This is a re generated print (not a simple photocopy) of what I believe to be the original handbook issued with the Astro Compass Mk II  and IIA ( RAF ref 6A/1174) during and after the last War. There is a serial code on the original suggesting Canadian printing in 1942. The original had no illustrations so I have, for clarity, added two of my own at the back. Several points suggest the original may have been a very small booklet similar to the Bubble Sextant's but untill I know the correct size I am printing it as A5. There are 16 pages A5, black and white with two illustrations. Subjects covered are:-  Principles of operation, Construction and field re tensioning of pivots,  Checking true heading by Sun, Moon, Planet and Star. Steering a course. Obtaining the true bearing of a distant object. Methods to check alignment of the compass. In fact, after reading the booklet you will probably assume everyone should have an Astro Compass, they are so usefull. I even have an article on converting one for use as a simple Dumpy Level!
There are other, American versions of the Astro Compass, the original being the British version developed by Mr. PF Everitt of  H. Hughes and Son. I have manuals for all of them, the Sperti Company  and WW Boes. If you suspect you have an American version mail me for identification.
For a more detailed view of the Astro Compass and some of the theory I would recommend reading AP 1234D, I do a reprint of the Astro compass section.
