Juha identified this meteo theodolithe as an Askania model but Seppo as a Vaisala model ???? :?
Seems that there are two separate models, with minor differences.


Askania

This one seems to be similar:

Picture SA 35552 in the mail on August 14 shows Finnish "kiertokaukoputki" = German "Rundblickfernrohr" = English "panoramic telescope", which is mounted on the artillery gun´s sight unit unit and used (mainly) for indirect firing i.e. fixing the gun traverse. Several makes and versions with minor differences in their construction were used by the Finnish Army. Juha´s mail of yesterday shows one of these.

Picture SA 37890 in the mail on August 17 shows Finnish "asemasuuntakehä" = German "Richtkreis" = English "aiming circle", which is used for determining firing positions and directions. The particular model shown is Tampella-designed "asemasuuntakehä 34 malli I", which was also manufactured by Valtion Tykkitehdas.
Thank you very much for your help, veeteetee . :)

There seem to be some (random?) differences among the ocular assembly, and the original Askania tripod seems to be slightly different, but I mainly ment these:
-the frame line
-the angular "attachment device"?
-the ballancing screw items

Askania's own pilot balloon theodolite seems to be different. Maybe the Väisälä model was designed and first built by Askania after Väisälä specification and later the production was moved to the low cost country Finland.

They both seem to be from Askania.

Maybe, maybe not.
Actually I don't remember seeing any theodolites (here) marked being produced by Vaisala.

V.Väisälä was a very small company making radiosondes, sounds unlikely they would have produced theodolites. Why it was called "Väisälä theodolite" in the company history may refer to the brother Yrjö Väisälä, active in optics and geodesy.
