Got it apart, now what to make out of it.

It's been rattling around in My tool box for to long. Was frozen up, got it free. Now what to make out of it? The only thing that comes to mind is a half base depth gauge. Any ideas?

Micrometer carriage stop.

I set one up on the down feed of my shaper when I was cutting the 6 kazillion teeth for the racks on my plasma table.

I can't tell from the pictures. If the markings start at 0.000 and then read larger as it is opened, like a normal micrometer, a depth gauge will be opposite reading. That will drive you nuts and leave you with the chance of miscalculating the actual depth. If that is the case you could use it to make your own deep throat micrometer. If it reads opposite to a normal micrometer, then it will do nicely as a depth micrometer.

It's difficult enough to change your thinking when using a depth mike without having to do some other conversion/arithmetic.

It reads the same as a regular mic, I already have a dial indicator set up for a lathe stop. I cannot let a good part sit idle, will keep on thinking!

While a dial indicator is handy, a micrometer stop is quicker when turning to a shoulder. You set the stop a few thousandths short of your final shoulder, run the carrige down to the stop each cut on the shank until the shank is the right size, make a note of the cross feed position, then back the stop back the few thousandths, and face off to final size.
I wouldn't be without mine. YMMV

With a dial indicator I set the dimension to what I want, turn dial to "0", chug away, maybe stop .001 away when finished turning move the carriage the last .001 and feed out.
