Just going through my notes and ran across this one from the other day.
I'm probably way off on my thinking of this.
But that's why I'm here at CCF to get some learning.
( If ) this is some kind of RPM.
Could there be two north of the regular MM?
The white arrows might've been first hit with the punch a little tilted towards the top?
The red arrows second punch tilted left and down?
(If) they are RPMs and two separate punches. Notice the white and red curves doesn't line up.
Sorry for my confusion of explanation.
Maybe I should've just posted new pictures.
Thanks for looking again and opinions.
