I finally have a lead for you. It does indeed have a split index
mirror. The instrument is a "vizeheliotrop". What is a vizeheliotrop? That
I don't know :-). There are some German web sites that describe it, but my
German is not up to the task. Here are a couple of photos I found of
the original instrument. This modified sextant may have been a precursor to the
heliotrope which Gauss invented during his survey of the Kingdom of
Hanover.
