    Yup...Imperial Japanese Navy,  a now sadly passed on relation of mine (a decorated USMC pilot) spent years stationed in Japan. 

    I too found Dreisenstok a remarkably compact and friendly cookbook method I could do out of the box with a pencil and get correct answers (always pleasing).   I initially learned on the ponderous  229 (Hardheaded determined to do things longhand), then a calculator.  If you throw the calculator overboard (or not), I want  Dreisenstok in my sextant box. 229 has lost any attractiveness since I've learned other tables and approaches.
