Search for an analog seismograph

I would like to buy or find for free, an analogue seismograph with a drum.

It is an old type of instrument and today superseded by analogue systems. Can anyone help me or advise me where I can look for?

Thank you.

Where are you from?

Hello Geobalocchi,

I think your best bet (after some internet research that yielded no positive results) would be to look for that specific seismograph on Ebay, if you haven’t already.

There may be some enthusiasts/collectors that have some units to sell.
