Doesn't matter it's broken, the cork isn't even attached anymore.
Can You Help Me Identify This Mystery Object?

It could work on a sphere, or on a boat, let's say to verify the amount of curvature.

An industrial boiler thermostat?

The object is a CORK. But, what the other gizmo is next to the cork I can't say. But, thanks for using it for scale.

It's a piece off an old tachometer.

It's a gizmo to measure profile, either concave or convex. As you turn the big nob, the numbers dial gives hieght or deapth, compared to the surrounding area.
I have to agree with SS.
If you rotate the knob so that the upper surface is in line with Zero on the scale, the center pin should be flush with the three exterior pins.

Retraction!!!!!! upon looking at the pics again, I retract what I said...... But I will say this I do believe it is some type of device to measure/calbrate...something, being in the process control field it looks as if it can be used in that capacity.

That's it, almost.
If I rotate the knob so that the disc aligns with the zero mark on the upright vernier scale and the disc is also at its zero mark when aligned with the vernier, or more easily, both show zero, then the centre pin is perfectly in line with the 3 fixed points.
The knurled knob below is a lock nut, obviously.
Yup, it does measure curvature!
Many, many thanks!
