What make and/or style ignition?

Okay guys, this car is new to me and on top of it this classic stuff is newer yet. My buddy's Uncle who is a big time Mopar racer around here wasn't entirely sure(he was looking at it through pictures sent via text message) but thinks it might be Pertronix. Does anybody know for sure what brand and/or style of set up this is? Also how does this setup differ from a factory style? Any help would be greatly appreciated.
