Brown &Sharpe #607..... picked up over the years. Some? folks make do with one. Part of the handle section unscrews to accept different length rods.... "I think" the sets come 0-12" but don't quote me. I like having these 3 which covers 90% of their usefulness,being too lazy to swap out rods.
You can use a dial caliper as a depth gage but,the small base makes it hard.... least for me? Use these for several key areas, dinking on guns and handloading. I record die height with them,as an example. Not really a hoarder,or a collector but love the Brown & Sharpe tools.... kind of,more from a "rescue" perspective?
