Hi kluz,

Do you know if this model was a native Swedish design or only manufactured under licence by Sweden ?

Here an image of the same model in Belgian use in 1940...

According to http://www.tjelvar.se/lv2/lv2-5.htm the Lyssnarapparat m/37A was made by Arenco and was very similar to the m/37, but it was made in Sweden.
Beställningar av Lyssnarapparater m/37A gjordes under åren 1938-43
hos Arenco i samverkan med Oskarshamns mekaniska verkstad.
Lyssnarapparaterna m/37 och m/37A liknar varandra i stort, m/37A är
emellertid svensktillverkad.

Hi Sturm 78,

yesterday late in the night I discovered Your question about this capßturedn bridge building material. It is the Russian material "N 2 P" M 1932 (понтонный парк Н 2 П 1932). Here an interesting site about this material:

Best regards

Hi, Bert. Thank you very much for your help and for the link.... :wink:
I did not expect an answer to this question, after 5 years of asking the question... :)

Thanks, Tommy. Therefore the Lyssnarapparat m/37 was a foreign design. Does somebody know any further information about this sound locator ?
I think French, probably...although the French Army used two models different to this one.... :?

Hi Juha

Ummhhh...I think that Czechoslovakia used Goerz sound locators designs, which were very different.... :roll:
Finland also used these Goerz sound locators

According manual of Anti-Aircraft Museum (Ilmatorjuntamuseo-opas) there were five sound locator designs used by Finnish military:
- Austrian m/39 Goerz
- Belgian m/40 Tepas
- German m/42 RHI - RHH (Ringtrichter - Richtungshörer)
- Italian Galileo m/43 manufactured by Strömberg Oy in Finland
- Captured Soviet m/42 (ET-2).

I would assume that at least the Tepas m/40 that is in collections of Anti-Aircraft Museum in Finland is Belgian made, since they list it as such.

Attached photo taken by yours truly in museum back in year 2002.

There are sound locator patents to a Czech TEPAS, KOMANDITNÍ SPOLEČNOST HARLAS A SPOL. V PRAZE, PRAHA (Vladislavova ul.13)
cf. e.g. http://spisy.upv.cz/Patents/FullDocuments/72/72875.pdf

TEPAS was for Technický průmysl akciová společnost; cf. https://books.google.fi/books?id=uK99Gg ... as&f=false

Well, It seems that for now the only thing clear is that the manufacturer of these sound detectors was a company named Tepas.

Perhaps some of these detectors preserved in museums have a nameplate of the manufacturer...which could clarify the question.

Seems that Tepas was behind the original idea.
Nameplates at museums clear the manufactures of the originals/under German rule? or the licence produced ones.
