This is a Fisher Porter Weighing Precipitation Gauge. From the serial number I think it was manufactured in 1967. 

One of my stations this year is due for an upgrade but recently (and just a few months before we install the shiny new up to date system) the existing precipitation gauge started acting funny. This data is super important to several people: weather nerds (obviously), farmers, the municipality, the fire ban people, etc.

So yesterday my manager helped me dust off and resurect an old one from The Warehouse of Sensors Time Forgot and today I put it in service. 

It was really neat to play with the old tech. It’s robust(ish) and it works.
