I'm wondering what this tool is called, and what it would be used for?
it's a Moore & Wright micrometer, It measures depth around 100mm +/-.
Ive had it for 30 years plus, can’t recall where it came from.
It looks like you can reduce depth measured using gauge blocks with holes in them.
Depth rod doesn’t appear to be removable.
