Dual Magnetic Dizzy Mopar Perf P4876735

Got this on a trade and can't find alot of info on this forum or the web in general about it so wanted to start a thread. Part number is P4876735. It's strange to me to have dual ignition box hook ups. Is it so you can run an Msd 6 on the street then an msd 7 at the track? Idk.

Just seeing if anyone runs a setup like this or has more info on the part. Thanks!!
