farm gizmo late 1800s??

[vanoldschool]

Found this Gizmo about 4 inches deep, The location is from the late 1800s, and From what I understand there was a farm there also a Military Installation. This Item is about 2 1/2 inches tall and has a small coil of thin wire on the inside, the base is threaded, I think mabe some sort of guage for an early tractor?? dunno

It's a bourdon tube for temperature measurement. The tube would bend when the temperatue changed and it would rotate a needle to indicate the temperature. It could be from a tractor but you usually see them in old mills or boilers. Anywhere temperature monitoring was critical. Hope this helps !!

It could also be a pressure gauge, Oil well gauges look like that as well, only pressure makes the tube expand and move the needle.
