Hi all,
A German WWI-era Flak rangefinder. Any idea about his official designation ?

Re: Id german optical equipment
It looks like this one: --Goerz, 1,25m Entfernungsmesser für Feldartillerie.-- But it appears to be a (slightly) bigger model, like 1,4m.
And of course it could be an identical Carl Zeiss model.
A much more similar, boxed model (Goerz, 1,4m) is shown here: http://www.militaria-fundforum.com/show ... p?t=840645
For comparison, here is again the 1,25m: http://firstwartechnik.free.fr/Dbinoall.html

Identifying the different models of rangefinders is quite complicated since they are all very similar and the photos are usually not very good ...

Do you know if the ranngefinder is the original Norwegian instrument of the battery or of German origin ?

Re: Id german optical equipment
Not my field of expertice, but I think a vertical rangefinder of some sorts.
Maybe the same as this (photos from the firecontrol-exibition at Oscarsborg castle, Norway)?

Re: Id german optical equipment
Those are variants of the "Depression" rangefinder. They work by measuring the angle to sea level at the target. The height of the rangefinder above sea level is known, so it's a simple trig calculation to get the range. These are sometimes called "base" rangefinders.
