    Wolfgang,

    Have you seen and tried any of them ?
    (I have not, even in the museums. Only pictures.)
    On my opinion, the main question is what accuracy can be actually
    achieved.
    With a simple star globe I can do to about 2 degrees.
    Some descriptions in the literature mention 1'
    ("Spherotrigonometer") but I don't believe this,
    especially for the devices which do a complete fix,
    rather than solve one triangle.
    
    Alex.
