They are also known as height gages, see the digital version here:

I don't know where the name cadillac gage comes from but it's what all the machinists I've ever worked with have called it so I picked it up from them. (Most of these machinest went through Pratt & Whitney's tool & die apprentice program so it probably comes from there.)


We have the old pre-dial indicator versions in our shop, it reads like a pre-dial vernier. As with most of our tools and tooling we got our equipment from either our primary sponsor upgrading or one of the other local UTC divisions upgrading their equipment. They used to essentially sell tooling by the pound or give it away. This leads to use having some really unique form tools for the mill, as well as stuff that we have no reason to keep other than its really cool like spline broach for a propeller.
