I can absolutely tell you what the "OLD TIME" Machinist called themSometimes the old timers called them "morphy" calipers. I have a few. If you notice,most old machinist's dividers have 1 leg longer than the other,to enable them to also do what morphy calipers do.

They are hermaphrodites we call them morphadites.
They are half caliper and half scriber for marking the distance from an edge in. When I say we call them it's because I am an old time machinist
having over 70 years experience
Well, I guess I'm an old geezer too because my 2-3 sets of "Old-time" calipers are used on a daily basis. I'm 53... Uh oh, what's going to happen when I get more experience .
