Appears to be made of brass and reminds me of a small wheel. The base still spins somewhat. Found near the site of an 1800's grist mill. Can anyone help me ID this thing?

It looks like a thermostat to me but can't tell you out of what though.

Thanks for the help, guys!!
Back in the oldie days they used to worry about engines running to cold or too hot so they put these thingamajgs in the radiator system and the would open an close at a certain temperaturbecaue eping the water or antifreeze just right for the baby bear engine to run puurfectly... If it was to cold it stayed closed and allowed the water jacket to heat up, when it got jut right it opened up and the coolant flowed thorugh a thing called a radiator (it radiates heat into the air) and the coolant was allowed to cool down and pumped back into the engine jacket,
These things sometimes went bad so they echanged them, they also came in summer and winter temperature ranges so people exchanged them depending on the season as well. Some folks would put the wrong one in and their radiator hoses would pop or their raditors would pop and leak out under pressure, Sometimes folks just took them out and forgot to replace them until winter when their engines never ran rightcold b ecause they were unable to warm all that water. up fast enough
Yep a brass thermostat is that..

Most definately a thermostat. The larger botton section sits in the block in the cooling system passages. It contains a bi-metal spring made to flex at a pre-determined temperature to maintain correct cooling system temps and open or close the passage of water through it to control the temperature. Most of the one's used today are set to maintain about 195 degrees in order for the engine and smog systems to work most efficiently. Dispite all the high tech in today's cars they work exactly the same way as when first invented.
