Nodody for my last question??

Well, here an image of an artillery optical sight (Zeiger-Zieleinrichtung 34) on an 15cm sFH18 howitzer.

Two images from EBay: Flak Em 4m R(H) rangefinder with a coupled device,
Identify by Xavier as a rudblinkfernrohr artillery sight trainer
Rundblickfernrohr Flak was a panoramic sight, used for aligning guns of a battery and their both fire directors.
The thing coupled with the rangefinder in this picture is the Berichtigungsgerät, a standard equipment (adjusting latch) of Em 4m R (H) 34 and 36 rangefinders, necessary for their adjustment.

Hello Sturm,

Why a Zeiger-Zieleinrichtung 34 ??? It's a Rundblickfernrohr 32, isn't it ?

Please note on the picture the non-optical sight in case of emergency !

Hello, Eax-E. Probably you are right...

Here, another image of a Flak Entfernungsmesser 36 (EM36) 1m rangefinder (I think)

Perhaps I can help with English nomenclature and functions for field artillery.

1. Theodolite. Used by topographic surveryors (map making) and artillery surveyors (providing accurate fixation and orientation over distance greater than a few km). Very precise instruments, scales typically to about 0.1 mil or equivalent in other units of measurement in horizontal and vertical planes on micrometer scales. Mounted on a field tripod.

2. Meteor theodolite. Used to track meteor balloons, for artillery meteor data capture. Not as precise as a survey theodolite. Mounted on a field tripod. Characterised by being able to measure in very high vertical plane, typically close to vertical as well as horizontal. Reduced precision compared to survey theodolite.

3. Director (UK English) or Aiming Circle (US English). Used in artillery batteries to orient guns in zero line or centre of arc (depending of national practice) and for short distance survey from a proper survey control point, sometime also found in OPs. Precision 1 mil or 5 minutes. May be capable of vertical angle measurement. Mounted on a field tripod. May be fitted with some sort of beacon light for night use (guns point their sights at the director to receive orientation).

4. Gun sights. For direct fire, eg anti-tank, a telescope similar to that used in a tank. UK versions were gun specific because the graticules were matched to the gun ballistics. Many guns also had an open sight (ie rifle-like).

5. Gun sights. Horizontal laying, Dial Sight (UK English), Panoramic Telescope (US English). Precision 1 mil or 5 minutes. Main scale could be 360 degs or 6400 mils, etc, or 180/3200/etc left and right. UK abandoned the L & R in the 1930s. Micrometer scale 1 mil, 5 mins, etc.

6. Gun sights. Vertical laying. This is where it starts to get complicated, it depends on whether guns were ordered range (yards/metres) and angle of sight (mils/minutes, etc), or tangent elevation (mils/minutes, etc) and angle of sight, or quadrant elevation. Dial sights/PanTels were mounted in a sight mount that could be cross-levelled (two axis). Vertical measurement needed a levelling bubble connected to the range or vertical angle(s) setting. This could be a separate instrument placed on a plane surface aligned with the axis of the bore, eg Gunners Quadrant (US English) or Field Clinometer (UK English). However, the sight mount could have a levelling bubble to show when the range or vertical angle, etc, set on the sight mount was reached. UK guns used the Sight Clinometer for this, which was also where the Angle of Sight (the angular difference in ground height between gun position and target position) was set. Of course UK guns also used calibrating sights that corrected the ordered range for the gun's muzzle velocity difference from standard.

7. Field Tripod mounted binoculars used by observers, (nicknamed 'donkey's ears' in UK) that could be used periscopically or wide to improve depth perception. Widely used by the German army, seldom seen in allied use although they were issued to UK batteries at least, but observers preferred hand held binoculars.

8. Flash Spotting instrument, UK and US used the same UK instrument with different names. Used by flash-spotting posts. Field tripod or table-top mounted binocular instrument, but not periscopic.

Hi all,

Another image of a German Flak Kinotheodolit

Nobody for the question raised by cuchoramone of 16 Jan 2014 and me of 02 Feb 2014, on the coincidence of the British and German design of these devices ??

Thank you very much for your help, Eax-E !! :wink:

A question of almost 3 years ago !! 8O :)

I guess it is a naval model, no? . Do you know the different models of naval rangefinders in use in the Kriegsmarine ?? :?

On the other hand, Any idea about this recce camera?

Yes it is. It must be adapted to very wet environment I guess.
I wish I know all KM rangerfinder, but it's not the case ! :lol:

No idea for the camera.
