Depth Micrometer

Damn, that is old. That company doesn't exist as anything but a brand anymore - and whoever owns it doesn't put on machine tools. Just landscaper's measuring tapes and the like.

I have a couple outside mics from that company that belonged to my great-grandfather - he worked in one of the shipyards in Virginia during WW2.

Got his copy of Machinery's Handbook, too. 12th edition. Plus a shitload of other stuff.
