Thank you, veeteetee

Which is the translation of "Tulenjohtosuuntakehä" in english?

Do you have any idea about the rangefinder of my last images ??

Regards Sturm78

[veeteetee]

Tulenjohtosuuntakehä = fire direction aiming circle, used by forward observers to give corrections to firing units.

[Sturm78]

Thank you, again,

But...according to your post of 21 Aug 2014, Asemasuuntakehäis is also a aiming circle.... What is the difference ??

Sturm78

[veeteetee]

Asemasuuntakehä is for firing post gun laying, tulenjohtosuuntakehä is for forward observer fire direction, both are aiming circles with some differences, of which I´m not quite sure.

On my mind it is photo of 1,25 m Goerz rangefinder. By the way, a number of Finnish AA-units were equipped by 40 mm Bofors guns and 1 m Zeiss rangefinders.

I'm sure you are right. Knowing the close relationship with Finnish 40 mm Bofors guns and 1 m Zeiss rangefinders I was just guessing that this one could also be a Zeiss product.

With best, J-P

Hi all,

Ummhhh......It is difficult to secure, but I would say that the rangefinder of my last images is slightly larger than 1m....

Hi all,

Two images from SA-Kuva archive (91329-90829):

Image 1: I am not sure; Soviet observation periscope TM82 ???
Image 2: cable winch ??

As customary for these questions, the original Finnish caption is rather revealing: "Säähavaintoasema toiminnassa. Semsjärvi 1942.01.16", in English "weather station in operation at Semsjärvi 16.01.1942". For speedier answers (= translations) it´s always a good idea to copy the original text even though you don´t understand a word of it.

And indeed, if you go to adjacent SA pictures - always a good idea, too - SA 90827-32 show the whole operation, including SA 90828, where a meteorological kite is being towed by this particular winch.

....I had never seen a meteorological kite, only meteorological balloons....


I know this is a complicated and little studied issue but..... maybe someone can identify the model or manufacturer of these three small rangefinders: they are three different models !!!

Any idea about the rangefinders ??
Here another image of one of these. I am not sure if this is the same model of SA-Kuva image 64217...
Any idea about the other optical instrument to the right of the image ?? TM 264 Tulenjohtosuuntakehä, mallia 18, jako 6000 ???

SA 90764:
The rangefinder is "TM 403 Stereo-etäisyydenmittari, mallia Zeiss, kanta 0,7 m" i.e. Zeiss stereo range finder with 0,7 m base.
Yes, the aiming circle is TM 264.

[Sturm78]

Any idea about the others rangefinders posted here on 15 Apr ??
