       The ambiguity is; does box refer to the sextant, or the case, and, does case mean a normal wooden box, or a leather pouch?


    ​The 'box' is the cylindrical drum into which the sextant can be housed when not in use.​
     
    ​That is my understanding of the term and Websters dictionary would seem to agree.​

      Marine and type mean nothing.


    ​I would demur. I think that the box sextant was originally a surveying instrument and, as such, did not need shades. A 'marine type' box sextant is a variant which has index mirror shades to enable it to be used as a nautical sextant.​
     

     I thought it fun to fly a 70 year old biplane, and use a 170 year old sextant, to investigate FC's 85 year old theories.


    ​I applaud you in this endeavour! ​The armchair expert must always give way to he who has tried it in the field (or even, in the air...)
