Just thought it would a good idea to talk more about E-messers.
Here is an example from Norway. Any clues what kind of one and which battery?

Hello
The picture is taken in Bergen, at Blåmanen. Its the rangefinder at MFA 802/4.
If im not mistaken they had a 6 M rangefinder.

Hello,
Thanks for answer. This one is for the same battery? It was described as Bergen.

[Andrzej Ditrich]

This one was described as belonging to Tirpitz(?) Looks like 4m.
For me it is attached on land - see the background.
This photo was bought

Yes, this is the same unit. Added a photo taken in 1950 (source:Bergenskart) I bough some photos some years ago from Blåmanen. Some was quite interesting as it show the rangfinder with several japanese visitors.

Thanks Stril.
Nice photo-map
Those photos with Japanes visitors (attache) are propaganda one and made by KB?

Next one:
I see it for the first time-beute one? Looks like 3m??? or 2,5m

Not sure if the photos was taken by a KB. They(3 photos) looks like snapshots. But the japanese visitors was also loooking at other sites, among those was MAA 504/11. Added one of the photos from Blåmanen and one from Fjelll. Showing one of the japanese visitors entering the triple turret.

I believe the background you see is the ship's bulwark or deckwalls. I'm almost certain that is a ship-mounted entfer likely on a upper-level tower platform. I'd have to see a schematic of the Tirp to be sure. Definitely KM crew. This is a "port-side" mount.

If you look closely again, you can see another entfernung unit directly behind this crew facing the opposite direction ("starboard") at the opposite station on the ship's observation platform. And then, again, if you look closely, you can see a third "fore" (towards the bow) observation station. The three stations all appear to have a step-up platform and it looks to be some upper-area tower location.

As for the entfernungsmesser itself, it appears to be a specialized design and the profuse and complex electrical connections and support arms are definitely shipboard. The dual-eyed telescopes you see (with the protective hinge-shield flaps) are similar, if not the same as, the Lichtsprechgeräte 80 glasses, which if I am correct, would make this particular device designed to to transfer audio signals on a light beam. The Li Spr system could connect telephone communication lines over enemy controlled areas or arduous terrain (such as the open ocean). The light beam projection required detection by a special receiver (another Li Spr), so this particular entfernungsmesser must have operated in such a way to establish voice communications with very distant ships or coastal installations and therefore be able to keep visual contact (and thus the communication signal) with the target at very far distances.

Maybe this application is also for tracking communications with aircraft equipped with the Li Spr system.

If they're not Li Sprs, then they might be standard RF 12 x 60s, because the objective ends look to be large enough, but they seem specially made for this unit, so I'm not completely sure.

Below 2 photos:

-E-messer Lehrgang-where? Swinemunde? I recognize wooden tower so it could be 20-30'.
-E-Messer in mobile configuration-not so popular subject of photos.

Re photo in post 1 and 3.
This is a Dreiwag with a 6 meter rangefinder. The Dreiwag (lit. Dreiwalzengerät) system was delivered by "Askania" and "Hagenuk", whilst the competing "Kleinkog" (lit. Klein-Kommandogerät) was a Zeiss product. The Dreiwag also came as Dreiwag Küste Schwer with an armoured cupola.

The photo in post 6 looks very much like a 3 meter Zerstörer range finder with the extra insulation making it unusually thick. This was also in use at some coastal batteries i Norway.

Tnx for detailed answer!
Insulation so obvious!

PS post-war Soviet rangefinders looked very similar to German
