Absolutely, and it is likely just the inner gimble . If you picture it with a second gimble to give freedom of movement, then sealed in a case with a tube vented to outside air pointing at the groves/vanes. The case is then subject to a vacuum and the tube "blows" the rotor and spins it up. It can be mounted with a spring instead of the second gimble to provide rate of turn.
A bit basic but they worked on early a/c and other things. Still in use on vintage aircraft, I worked on a 30s Beechcraft a few years back and the "auto pilot" was also vacuum and pressure operated with bellows etc. Sorry, my original trade...🫢
