By chance, I found this on the internet:
https://tidsskrift.dk/frakrigogfred/issue/view/3755
Choose the PDF article: Hit First, hit hard, etc by Søren Düwell.
Danish text and english summary.
On WWI german and english navy artillery rangefinders and firedirection technology.
For me, it is the first time I have seen a german navy rangefinder with "Heruntergeführter Okularen".
Meaning a rangefinder where the oculars has been mounted well below the actual instrument.
There are a couple of other interesting items as well.
I haven´t checked if Mr Düwell has made an englsih version of this.
( or other articles.)
But just the photo´s are pretty interesting to me.
Enjoy.
