Well, after that sales pitch, I had to buy the book. Kindle edition only, my bookshelves are full. The only problem with Kindle is finding a page number. How much you see seems to vary with the size of your PC/smartphone. Please give more clues, e.g. Chapter, or between which diagrams.
Actually, while searching to find which of your publications I’ve already downloaded and now lost inside my PC, I came across this on page 8 of ‘My Modern Sextant’ by Heath & Co, price one shilling and sixpence.
