Hi All, I was hoping I could get some assistance regarding a railroad gauge I have acquired.

The device is a Kongsberg Tellus Type Vibration Gauge (pics attached) the only reference I can find online is that they have one in the Norwegian Railway Museum and it shows on their digital archive.

What I know so far is that it was manufactured by Kongsberg Vapenfabrikk of Norway, a munitions works with rail and track divisions (silver mines as well as large stock trains) the meter is of extremely sturdy build and is housed within a wooden fitted case, a screw at the side releases a large stone plate attached to a spring for measuring vibration, the results are written to a spinning tachograph disc, all powered by a D size battery. Included is a picture of the device set up, mini spanner and screwdriver.

Despite a good hour or two trawling results in English and Norwegian I have been unable to find out much, does anyone have any experience of a similar piece of kit ?

Thanks in advance for any assistance, pics below.
